Physics & Astronomy

 

Leading Discoveries Across Space, Time, and Matter

We explore the cosmos at every scale—from the smallest particles to the farthest galaxies—and turn curiosity into discovery. In our classrooms, laboratories, and observatories, ideas move freely across physics, astronomy, and applied science. Whatever sparks your curiosity, you’ll find the tools to explore it here at LSU.

Research that spans the Universe

At LSU, physicists explore the laws of nature across an extraordinary range of scales, from quantum matter and subatomic particles to stars, galaxies, and the cosmos itself.

Our faculty and students work across condensed matter and quantum materials, nuclear and high-energy physics, astrophysics and cosmology, medical physics, and computational science. Together, we pursue fundamental questions, develop new tools and technologies, and prepare the next generation of scientists.

Research Highlights

LSU physicists developed a room-temperature multiphoton quantum reservoir that uses classical light and photon-counting measurements to process information, simulate complex quantum dynamics, and learn mathematical functions while remaining robust to noise and loss.

LSU physicist Constantin Schrade will receive a DOE Career Award to explore how altermagnets, an emerging class of magnetic materials, could be used to control the movement of electrons based on their spin. The research builds on his recent work published in Science Advances and could help advance spintronics, a promising approach to developing more energy-efficient computing technologies.

LSU physicist Constantin Schrade and collaborator Mathias S. Scheurer have developed a new theory for controlling how electrons move through altermagnets, an emerging class of magnetic materials. Their work shows that changing the material’s microscopic magnetic patterns could steer electrons in different directions depending on their spin. The findings give scientists new predictions to test and could eventually help researchers control how spin-based information moves through future electronic technologies.
