Description

Condensed Matter Physics

Our research group is based in the Geballe Laboratory for Advanced Materials at Stanford University. In broad terms, we study materials with unconventional magnetic and electronic properties, with the general aim of obtaining a deeper understanding of the many effects that can emerge from electron correlation. We employ several techniques to grow high-quality single crystals of materials of interest. Experiments probe the thermodynamic and transport properties of these materials, often in high magnetic fields. Current interests include superconductivity, topological insulators, aspects of quantum magnetism, and the behavior of electrons in low-dimensional materials.
