- An ICAM workshop entitled "Novel Emhttp://www.phys.lsu.edu/ICAM/ergent Phenomena Created by Spatial Confinement", organized by our research group, was held at LSU on October 27-30, 2010. The focus of this workshop combines two of the major material themes of the 21st century—nano and complexity with the expectation the new emergent phenomena will appear. The challenge and the opportunity is to use what we learn to either design or discover new materials or new functionality. There were approximately 50 participants attending the workshop coming from the United States, Asia, and Europe. The workshop had a total of 20 invited talks with extended times for exciting discussions. Professor Thomas Klei, the LSU Interim Vice Chancellor of Research & Economic Development, gave the welcome speech at the workshop. This workshop was dedicated to Professor E. Ward Plummer, who turned 70 at the end of October 2010. Ward has a central scientific concern of combining the knowledge from surface physics with materials science in order to gain a better understanding of emergent phenomena in complex correlated electron materials driven by broken symmetry and spatial confinement. This class of materials include high-temperature superconducting copper oxides and newly discovered iron-based superconductors. We also had a birthday celebration for Professor Plummer at Nottoway Plantation. The entire event was a complete success.

- RESEARCH NEWS! - Condensed Matter Physics - Ward Plummer and his colleagues have demonstrated that self-assembled nanostructures (SANs) can be used to fabricate the worlds smallest capacitor, setting up the stage for investigating unusual electron behavior and exploring unique opportunities for energy applications. The SANs consist of pairs of 10 to 20-nm long lines separated by 1.2 nm and act as a quantum well on the surface TiO2(110). Inside the quantum well, a long wavelength oscillatory feature of the local density of states is observed at room temperature by scanning tunneling microscopy and attributed to the formation of electronic standing wave for the lowest energy quantum state using first principles calculations. This observation is the first attempt ever made to experimentally image the transition from a strongly correlated regime in a zero-dimensional system to a quasi-independent particle or band-like behavior in an extended one-dimensional system. TiO2 is an important energy material as it is one of the main support used in industrial catalytic reactions. The unusual electronic behavior demonstrated here opens up new possibilities for highly efficient chemical reactivity with unprecedented applications in energy conversion and harvesting. ABSTRACT -- RESEARCH ARTICLE
- RESEARCH NEWS! - As part of a program to develop a model of quantum cosmology, Kristina Giesel and colleagues from the University of Warsaw have proposed a new theory to describe the evolution of space-time in the very early Universe. Their paper (in Phys. Rev. D 82, 104038) describes their approach to couple the gravitational field to a scalar field using loop quantum gravity techniques to complete the quantization.
The U.S. Army Medical Research Acquisition Activity (USAMRAA) recently awarded Mary Bird Perkins Cancer Center and LSU (Ken Hogstrom, PI) a $2.2 million research contract to fund proton therapy research that could result in targeting cancer treatments more effectively. A major advantage of proton therapy comes from the possibility of delivering high radiation doses to a targeted tumor while sparing surrounding healthy tissues and organs. Additional work on bolus electron conformal therapy, a new electron beam technology for individualized treatment of skin cancers, is described in the recent issue of Mary Bird Perkins Perspective.

- RESEARCH NEWS! - As described in a recent Gemini Observatory newsletter, luminous infrared galaxies (LIRGs) at high redshift contain great amounts of dust, but a complete account of the origin of the dust so early in the history of the universe remains lacking. Jen Andrews, Geoff Clayton, James Clem, Joey Chatelain, Joe Gallagher et al. have found evidence for early dust formation in a supernova remnant, but the quantity means that supernovae are not likely the primary source of dust in LIRGs, even allowing for dust formation in circumstellar interactions as well as in the ejecta. Their results are published in the Astrophysical Journal 715, 541 (2010).

RESEARCH NEWS! - The journal Classical and Quantum Gravity highlights a community paper called "Testing Gravitational-Wave Searches with Numerical Relativity Waveforms: Results from the First Numerical Injection Analysis (NINJA) Project" with authors from many institutions, including several current and former members of LSU's Relativity Group. The article represents the first large-scale collaborative work between the data analysis and numerical relativity communities towards measuring and recognizing the gravitational waves expected in the merger of a binary black hole system in the data from detectors in operation (e.g., LIGO). For several years, the numerical relativity community has been working towards obtaining such waveforms - which required constructing complex codes implementing Einstein's equations - while the data analysis community has developed a series of refined tools to analyze the data from interferometric detectors. This article presents the first cohesive effort to adopt the knowledge gained through the simulations and study its incorporation in data analysis pipelines, measuring efficiency in simulated gaussian data."

- Research News! - D. Uskov and A. R. P. Rau: Geometric phases and Bloch-sphere constructions for SU(N) groups with a complete description of the SU(4) group", Phys. Rev. A 78, 022331 (2008), provides a geometrical view of two-spin quantum systems. The quantum system of a pair of spins (qubits) lies at the heart of quantum computing, quantum cryptography and related areas of current research. This paper develops a geometrical picture for the time evolution of such systems that closely parallels a similar picture, called the Bloch sphere, which has been very influential over the decades for the quantum mechanics of a single spin in magnetic fields. This latter picture of a unit vector rotating on a sphere provides both basic insight into magnetic resonance and guides its applications in chemistry, biology and medical magnetic resonance imaging. Extension to two (or more) spins provides analogous geometrical objects, albeit of higher dimension, including spheres of larger dimension. The quantum evolution is mapped into that of real vectors rotating on such geometrical manifolds.

- RESEARCH NEWS ! - By replacing a few percent of iron atoms with manganese in the semiconductor ferrosilicon (FeSi), John DiTusa, former student Ncholu Manyala, and colleagues have demonstrated a possible method for systematically inducing non-Landau Fermi liquid behavior in doped semiconductors. ("Doping a semiconductor to create an unconventional metal", Nature 454, 976, 2008). See also the News and Views article "Materials Science: A metal left spinning", Nature 454, 951 (2008). The effect is apparently due to too few mobile electrons to compensate for the spins of unpaired electrons on the impurity atoms. The behavior can be turned on or off by applying a magnetic field at low temperature. More information.
- Ph.D. student, Jennifer Andrews has been awarded a NASA Graduate Student Researchers Program (GSRP) Fellowship for her thesis research on "A Multi-Wavelength Study of Dust Production in Type II Supernovae." She has also been successful in applying for observing time on the Hubble Space Telescope, Spitzer Space Telescope, and at the Gemini Observatory.
- RESEARCH NEWS ! - Three papers by the theoretical and experimental gravity group have been highlighted by the editorial board of the journal Classical and Quantum Gravity this year:  In "Rotating collapse of stellar iron cores in general relativity" (Class. Quantum Grav. 24, S139 2007), B. Zink, E. Schnetter, and colleagues present the results of simulations of the collapse of rotating stellar iron cores, focusing on the gravitational wave emission during the collapse, core bounce, and post-bounce phases.  In "Late-time tails in the Kerr spacetime" (Class. Quantum Grav. 25, 072001, 2008), Jorge Pullin and colleagues describe the decay with time of perturbation fields outside a black hole.  In "Search for gravitational-wave bursts in LIGO data from the fourth science run" (Class. Quantum Grav. 24, 5343, 2007), the LIGO Science Collaboration (including R. Amin, L. Blackburn, J. Giaime, G. Gonzalez, C. Hanna, W. Johnson, A. Rodriguez, J. Slutsky, and M. Sung at LSU) describe the results of the fourth science run with the LIGO and GEO 600 gravitational wave detectors. With significantly lower noise and greater sensitivity than previous runs, no positive signals from supernova or binary black hole merger events were detected. The theoretical gravity group has made the Classical and Quantum Gravity highlights list every year since the groupt started at LSU in 2001!
- RESEARCH NEWS ! - The binary pulsar system PSR J0737-3039A/B consists of two closely spaced neutron stars in an edge-on configuration such that one pulsar eclipses the other once in every 2.45 hr orbit. The spin of one compact rotating star couples with the orbital angular momentum and the spin of the other, analogous to spin-orbit and spin-spin coupling in an atomic system, providing a test of general relativity in the strong-field regime. The relativistic spin precession of pulsar B has now been measured to be about 4.80/year, R. Breton et al., Science 321, 104, 2008 , in agreement with the prediction of 5.10/yr made by B. Barker and R.F. O'Connell, Phys. Rev. D12, 329 (1975), within an observational uncertainty of 13%. See also R.F. O'Connell , http://arxiv.org/abs/0804.3806 (2008) which reviews both strong and weak-field tests. The terminology spin-orbit and spin-spin in the gravitational context was introduced by R.F. O'Connell, in Experimental Gravitation:Proceedings of Course 56 of the International School of Physics "Enrico Fermi," B. Bertotti, Ed. (Academic Press, New York, 1974), p. 496.
- RESEARCH NEWS ! - The Auger Collaboration (including Jim Matthews, Alexei Dorofeev, Javier Gonzalez at LSU, and Megan McEwan, Roger McNeil, and Rishi Meyhanden formerly in the department) has published evidence for a cutoff at the high end of the cosmic ray spectrum. Auger previously showed that the arrival directions of cosmic rays at energies above 6 x 1019 eV were correlated with the directions of Active Galactic Nuclei -- i.e., that the highest energy cosmic rays are extragalactic in origin. Now, at the same energy, Auger has demonstrated the presence of the predicted GZK cutoff due to the interaction of extragalactic protons with the cosmic microwave background. The scientific article appears in Physical Review Letters 101, 061101 (2008). A commentary by Mike Cherry appears on the APS Physics Viewpoint web site.
- RESEARCH NEWS ! - LSU and Florida State University (FSU) are collaborating to develop the Array for Nuclear Astrophysics Studies with Exotic Nuclei (ANASEN). ANASEN combines three different types of detectors to achieve an efficient and selective instrument for studies of nuclear reactions induced by low intensity beams of exotic nuclei. Solid-state and gaseous detector technologies are being developed with state-of-the-art electronics systems to provide accurate measurements of the energies and trajectories of charged ions over a large angular range. Students at LSU and FSU will develop and test detector elements that will be combined into a completed array and used in experiments with beams of exotic nuclei at the Fox Superconducting Accelerator Laboratory at FSU. ANASEN will allow new direct measurements of nuclear reaction cross sections that are important for understanding stellar explosions like X-ray bursts and the structure of short-lived nuclei. ANASEN will also be a portable instrument that will be moved to the National Superconducting Cyclotron Laboratory at Michigan State University and potentially to other laboratories. LSU and FSU students will have a unique opportunity to conduct leading research in nuclear physics and nuclear astrophysics with ANASEN at major national accelerator facilities. Students will also gain invaluable hands-on experience in forefront instrumentation and techniques that are important for various fields from health care to national security. ANASEN is funded by the by the National Science Foundation's Major Research Instrumentation Program and by LSU and FSU, and led at LSU by Jeff Blackmon.

The scientific paper can be found here. A popular writeup can be found here.
- RESEARCH NEWS ! - Titanium dioxide (TiO2) has a number of uses in catalysis, photochemistry, and sensing that are linked to the reducibility of the oxide. Usually, bridging oxygen (Obr) vacancies are assumed to cause the Ti 3d defect state in the TiO2 band gap. Phil Sprunger and colleagues from the Interdisciplinary Nanoscience Center, Department of Physics and Astronomy, and Institute for Storage Ring Facilities at the University of Aarhus in Denmark propose that Ti interstitials in the near-surface region may be largely responsible for the defect state in the band gap. Based on data from high-resolution scanning tunneling microscopy and photoelectron spectroscopy measurements, they argue that these donor-specific sites play a key role in and may dictate the ensuing surface chemistry. Density functional theory calculations support the experimental observations. The scientific paper was published in Science 320, 1755 (2008).

- RESEARCH NEWS ! - LIGO Sheds Light on Cosmic Event - The non-detection of gamma ray burst GRB070201 by LIGO indicated that this event was not caused by the merger of two neutron stars or black holes, contrary to the expectations for a short-duration gamma ray burst observed in a nearby galaxy. The scientific article can be found here.
- RESEARCH NEWS ! - LSU Faculty are involved in two of the top 10 physics stories of the year according to the list published by the American Institute of Physics. LSU faculty are involved in the MiniBooNE experiment and the Auger experiment. MiniBoone (which involves Professor William Metcalf and his research group) recently showed evidence that appears to rule out a fourth generation of neutrinos. Previous measurements of neutrino oscillations had provided tentative evidence for a family of "sterile" neutrinos; MiniBooNE has ruled that out, leaving only the standard three neutrino families associated with the electron, muon, and tau particles. Auger, the world's largest cosmic ray telescope, involves Professor James Matthews; Auger has provided the first direct evidence that the highest energy cosmic rays are produced by active galactic nuclei powered by massive black holes at the cores of galaxies.

- RESEARCH NEWS ! - At the 209th meeting of the American Astronomical Society in Seattle, Washington, astronomers announced findings of unusually high levels of the oxygen isotope 18O in two extremely rare types of stars. This breakthrough has led astronomers to believe that the origin of these odd stars could be the merging of white dwarf stars, the burnt-out remnants of normal stars like the Sun. Read the entire article in our Fall 2007 departmental newsletter. For more information, The Gemini Observatory website press release can be found here. The Gemini press release recorded more hits (more than 50,000) in the first three months after its release than any previous Gemini press release.
- RESEARCH NEWS ! - "The Pierre Auger Observatory: Measuring the Highest Energy Cosmic Rays" - In July 2007, the initial Auger results were presented at the 30th International Cosmic Ray Conference in Mexico. The data indicated a clear cutoff in the spectrum near 1020 eV, a result known as the "GZK cutoff" and expected due to interactions of high energy cosmic ray protons with the cosmic microwave background. The Auger Collaboration consists of over 200 scientists from more than 20 countries. The group participating from LSU is led by Prof. James Matthews and includes Prof. Roger McNeil, postdocs Alexei Dorofeev and Javier Gonzalez, graduate student Megan McEwen, and undergraduate students Rachel Mannino and Brittan Farmers. Prof. Matthews has been a part of the project since it was first conceived in 1992. More information about Auger can be found by visiting Nature.com, Science Magazine, or the Auger Observatory website. Read the entire article in our Fall 2007 departmental newsletter.

- RESEARCH NEWS ! - "The Relativistic Turducken Approach to Stuffing a Black Hole" - Erik Schnetter, Manuel Tiglio, and Peter Diener from LSU's Physics and Astronomy Department and the Center for Computation and Technology, working together with colleagues from the Universidad Michoacana de San Nicolas de Hidalgo in Mexico, North Carolina State University, the University of Southampton in Britain, and the Albert Einstein Institute in Germany, have shown how to stuff a black hole. The result is that their "turducken" approach to stuffing a back hole may lead to useful methods of simulating the behavior of real black holes irrespective of many of the unobservable details of how the interior stuffing is arranged. A preprint of the paper can be found on the web. More information can be found in the article in our Fall 2007 departmental newsletter.
- RESEARCH NEWS ! - "Medical Physics is a fundamental science concerned with improving people's lives," said Dr. Polad Shikhaliev, who joined the LSU faculty in January, 2007 as an Assistant Professor in its joint Medical Physics Program with Mary Bird Perkins Cancer Center. "Medical Physics has a direct impact on people's health, helping cure breast cancer. As a medical physicist, I conduct research with detector technology to find cancer earlier". Dr. Shikhaliev's current research is focused on developing a new breast CT system that will allow detecting breast cancer at its very early stages. Breast CT, as proposed by Dr. Shikhaliev, should be able to detect breast lesions as small as 2-3 mm, compared to 10mm, which is often the case in current mammography x-rays. He also expects his research to acquire the CT scan with less radiation dose to the breast than current low-risk mammography techniques and with no pain or discomfort.

Prof. Bradley Schaefer has just won a share of the 2007 Gruber Cosmology Prize as a particiapant in the discovery that the expansion of the Universe is accelerating, not decelerating as expected. By measuring the brightnesses of a large number of very distant supernovae, two competing teams -- the Supernova Cosmology Project and the High-z Supernova Search team -- simultaneously determined that the expansion of our Universe is accelerating, a surprising result since confirmed by several independent methods. The conclusion is that approximately 70% of the mass/energy of our Universe is due to a previously unknown 'force' now called 'Dark Energy'. The $500,000 prize money will be shared amongst the co-authors of the original papers, with the award ceremony being held on 7 September 2007 at Trinity College in Cambridge. Past winners of the Gruber Cosmology Prize are John Mather and the COBE team, Martin Rees, Vera Rubin, and Allan Sandage. The Gruber Award is described in more detail here. - - posted August 7, 2007
