Department of Physics and Astronomy. It is a leading academic unit within the University of California, Los Angeles, dedicated to advancing knowledge in the fundamental laws of the universe and the nature of celestial objects. The department is renowned for its contributions to particle physics, astrophysics, and condensed matter physics, fostering a collaborative environment for discovery and education. Its faculty and alumni have been recognized with prestigious awards including the Nobel Prize in Physics and the Breakthrough Prize in Fundamental Physics.

History

The department was formally established in 1965, consolidating pre-existing research groups in physics and astronomical studies at UCLA. Its early growth was significantly influenced by its involvement in major national projects like the Manhattan Project and post-war research funded by the National Science Foundation and the United States Department of Energy. A pivotal moment came with the recruitment of renowned scientists such as David Saxon and Julian Schwinger, the latter joining the faculty after winning the Nobel Prize in Physics for his work on quantum electrodynamics. The department's astronomical research gained substantial infrastructure with the development of its observational facilities and partnerships with institutions like the W. M. Keck Observatory and the Las Cumbres Observatory Global Telescope Network.

Academic programs

The department offers comprehensive degree programs including a Bachelor of Science in Physics, a Bachelor of Arts in Physics, and a specialized Bachelor of Science in Astrophysics. At the graduate level, it confers Master of Science and Doctor of Philosophy degrees in Physics, with research specializations ranging from string theory to observational cosmology. The curriculum is designed to provide rigorous training in classical mechanics, electromagnetism, quantum mechanics, and statistical mechanics, often involving collaborative courses with the Department of Mathematics and the Henry Samueli School of Engineering and Applied Science. Students frequently engage in research through the California NanoSystems Institute and the Institute for Quantum Information and Matter.

Research areas

Primary research thrusts are organized into several key groups. The high-energy physics group conducts experiments at facilities like the Large Hadron Collider at CERN and the SLAC National Accelerator Laboratory. Astrophysics and astronomy research focuses on areas such as exoplanet detection, gamma-ray bursts, and galaxy formation, utilizing data from the Hubble Space Telescope and the Chandra X-ray Observatory. The condensed matter physics group investigates superconductivity, topological insulators, and nanomaterials, often in collaboration with the IBM Thomas J. Watson Research Center. Theoretical research spans cosmology, quantum gravity, and particle phenomenology, with strong ties to the Kavli Institute for Theoretical Physics.

Faculty and staff

The department's faculty includes numerous distinguished scientists and award winners. Notable members have included Nobel laureates Julian Schwinger and Willard Libby, as well as recent faculty like Andrea Ghez, who received the Nobel Prize for her discovery of the supermassive black hole at the center of the Milky Way. The staff supports research operations across major grants from the National Aeronautics and Space Administration, the National Institutes of Health, and the Alfred P. Sloan Foundation. The department also benefits from adjunct faculty and researchers affiliated with the Jet Propulsion Laboratory and the Lawrence Berkeley National Laboratory.

Facilities and resources

Key facilities include the UCLA Physics and Astronomy Building, which houses advanced laboratories for optics and laser research. The department operates the UCLA Infrared Laboratory for detector development and maintains a high-performance computing cluster for simulations in computational astrophysics. Students and researchers have access to the UCLA Planetarium and the UCLA Observatory atop the Mathematical Sciences Building. Major instrumental resources are provided through partnerships with the W. M. Keck Observatory in Hawaii and the Atacama Large Millimeter Array in Chile.

Notable achievements

Faculty achievements have been recognized with the highest honors in science, including Nobel Prizes awarded to Julian Schwinger, Willard Libby, and Andrea Ghez. The department played a crucial role in the LIGO collaboration's first detection of gravitational waves from a binary black hole merger. Researchers here made seminal contributions to the understanding of dark energy through the Sloan Digital Sky Survey and helped develop the COBE satellite experiments that mapped the cosmic microwave background. Its educational programs have produced notable alumni such as F. Sherwood Rowland, a Nobel laureate in Chemistry, and Michael L. Brown, a leading planetary scientist.
