Probing Quantum Dynamics with Strongly-driven Ultracold Gases
Given by: Dr. David Weld of the University of California, Santa Barbara
Statistical mechanics provides a powerful framework for understanding the equilibrium properties of matter. Controlling and predicting the behavior of matter away from equilibrium, however, remains a major theoretical and experimental challenge. Atoms cooled to a few billionths of a degree above absolute zero offer a useful tool for exploring this frontier, and a nearly ideal context for the creation and control of nonequilibrium many-body quantum systems. I will discuss results from a sequence of recent experiments on cold atoms away from equilibrium, starting with the engineering of band structure and transport properties in a shaken lattice, moving on to the first experimental realization of a relativistic harmonic oscillator, and concluding with the observation of anomalously slow heating in prethermal driven interacting quantum matter.
