Ultracold quantum gases: Shedding new light on many-body dynamics and entanglement

Main list: Physics and Astronomy Colloquia

Abstract

Prof Andrew Daley
University of Strathclyde, Quantum Optics and Quantum Many-body Systems

Over the course of the last two decades, experiments with ultracold atoms and molecules have developed to a level where we have strongly interacting quantum gases that are controllable and measurable on a single-particle level. This now allows us to engineer a range of fundamental models from solid state physics in experiments, and explore their properties cleanly on a microscopic level.

 

Beyond textbook demonstrations of equilibrium and single-particle properties (including insulating phases, magnetic superexchange, and Bloch oscillations), this now enables us to explore fundamental aspects of non-equilibrium dynamics in quantum many-particle systems. These range from from the approach of systems to equilibrium, and thermalisation in statistical mechanics, to the influence of the environment and decoherence in open many-body quantum systems.

 

I will give an overview of recent developments in these areas, and touch on the recent measurement of many-body entanglement with ultracold atoms in optical lattices.
