Bio/Description
Professor of Electrical and Computer Engineering
Associated Faculty in Physics
My research specialty is theoretical condensed matter (solid-state) physics. In recent years, our group has worked mainly on the physics of topological materials, most especially the quantum Hall regime of two-dimensional electronic systems (e.g. semiconductor heterostructures or graphene, subject to a strong perpendicular magnetic field). We also study highly disordered electronic and magnetic systems (exploring phenomena such as single-particle and many-body localization), as well as solid-state systems for spin-based and topological quantum computation.
Our research combines analytic and computational methods, including the concept of scaling, Density Matrix Renormalization Group, Strong Disorder Renormalization Group, Monte Carlo Methods, Transfer Matrix Methods and Sparse Matrix Diagonalization.
Professor Bhatt was Director of the Princeton Center for Complex Materials (1999-2005), Faculty Fellow and Acting Associate Director of the Princeton Center for Theoretical Science (2005-2012), and prior to joining Princeton, Head of Theoretical Physics Research at Bell Laboratories.
