Thomas Quella

 

My research interests are broadly defined to be in the field of mathematical physics and theoretical physics, specifically mathematical aspects of quantum condensed matter physics, quantum field theory and statistical physics. This includes, in particular, theoretical research in the fields of quantum spin liquids, fractional quantum Hall systems, topological insulators, tensor network states and conformal field theory.
