Bio

Professor Brown received his B.S. from the University of Colorado in 1981. He obtained his Ph. D. from UCLA in 1988, working on Dynamics of Incommensurate under Dr. George Gruner. He taught at the University of Florida from 1989 – 1992. Currently, Dr. Brown is a Professor of Physics at UC Los Angeles.

Abstract

Nuclear magnetic resonance is a widely applied local probe because of its sensitivity to magnetic and charge environments in molecules and materials. A familiar application in condensed matter physics is in the identification and study of broken symmetry states-such as in magnetic, distorted, or charge-ordered phases-using a combination of spectroscopy and relaxation methods. The approach is often uniquely valuable in circumstances where experimental conditions might preclude the use of other techniques, such as in high pressure or high magnetic field environments. Discussed here are two problems in superconductivity, where the extreme condition of either high magnetic field or uniaxial stress is exploited. In the first case, quasi-2D organic conductors are studied as a host platform for FFLO physics, and in the second case we re-examine the case for topological p-wave superconductivity in Sr2RuO4.
