Personal Background
Stephen B. Libby is the Theory and Modeling Group Leader in the Physics Division at Lawrence Livermore National Laboratory. His current research is devoted to novel quantum coherent technologies and high energy density physics. The work on quantum devices involves the development of high precision atom interferometer gravity and gyroscopic sensors for security and navigation applications in collaboration with AOSense, work with the NIST ion storage quantum information group on improved ion trap gate physics, and ‘home grown’ LLNL quantum computing. In high-energy-density physics, he co-developed accurate, highly accelerated algorithms for non-equilibrium radiation transfer. He received his B.A. from Harvard University in 1972, and his Ph.D. in physics from Princeton University in 1977 as a student of David J. Gross. He performed postdoctoral work at the Yang Institute for Theoretical Physics at SUNY at Stony Brook and worked as a research assistant professor at Brown University. During this period, he worked on quantum chromodynamics, developing key factorization theorems with George Sterman, and the theory of quantum Hall effect transport, discovering the scaling theory with Herbert Levine and Aad Pruisken. Beginning work in applied physics in 1986 at LLNL, he focused on x-ray laser research, becoming the design group and program leader. He was also a consulting professor at Stanford University from 1992–1994. He served at the Department of Energy (DOE) as the Defense Programs LLNL "Science Council" member and in the Advanced Strategic Computing Office. He was also a member of the National Research Council "Rare Isotope Science" committee. He was awarded a DOE Defense Programs Excellence Award in 2014 for work on equations of state. Libby is a fellow of the American Physical Society and holds a certificate in international security from Stanford University. He became an LLNL Distinguished Member of the Technical Staff in 2022.
