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
Led by LSU Boyd Professor Gabriela González, a new $4 million, two-year National Science Foundation grant will support the computing infrastructure behind the Laser Interferometer Gravitational-Wave Observatory (LIGO). The collaborative project will improve data analysis, accelerate alerts to astronomers, and maintain the reliable computing systems essential to detecting gravitational waves from colliding black holes, neutron stars, and other cosmic events.
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.
