[PAST EVENT] Physics Colloquium
November 8, 2013
4pm - 5pm
Abstract:
At a quantum phase transition, one ground state evolves into a different one by passing through a quantum critical region with enhanced spatial and temporal fluctuations. I will discuss several ways of probing the quantum critical fluctuations in a system of strongly interacting bosons in optical lattices using deviations from the fluctuation-dissipation theorem. I will also discuss some novel ways of using atom-photon entanglement to detect correlated phases.
