Research Interests

Non-relativistic Critical Phenomena

At a quantum critical point, space and time need not scale in the same way. I am interested in quantum critical phenomena with anisotropic space-time scaling, including Lifshitz critical points. In particular, I study how the dynamical critical exponent is constrained and how it is reflected in low-energy excitations and correlations.
