Ph.D., Physics, University of Illinois at Urbana-Champaign, 2007
Summary:

My research focuses on describing and controlling dynamics of quantum many-body systems. My goal is to address some of the fundamental problems of ultracold atom and condensed matter physics:
  1. What are the generic alternatives to thermalization?
  2. Interplay of pseudo gauge-fields, topology and dynamics
  3. Dynamics of mesoscopic systems and (with and without non-Abelian excitations)

Addressing these fundamental physics questions will have important implications for: (1) understanding the limitations and alternatives to thermodynamics, (2) generating non-Abelian excitations in static ultracold atom systems and building photonic crystals with broken time-reversal symmetry, (3) control over non-Abelian excitations will be useful for building quantum memory and quantum computers.
