The quasi-normal modes of quantum criticality
William Witczak-Krempa, Subir Sachdev
We study charge transport of quantum critical points described by conformal field theories in 2+1 spacetime dimensions. The transport is described by an effective field theory on a…
Pyrochlore electrons under pressure, heat and field: shedding light on the iridates
William Witczak-Krempa, Ara Go, Yong Baek Kim
We study the finite temperature and magnetic field phase diagram of electrons on the pyrochlore lattice subject to a local repulsion as a model for the pyrochlore iridates. We prov…
Gauge-field fluctuations in 3D topological Mott insulators
William Witczak-Krempa, Ting Pong Choy, Yong Baek Kim
We study the low-energy properties of three-dimensional (3D) topological Mott insulators which can be viewed as strong topological insulators of spinons interacting with a three-di…
