Title

Quantum simulation with ultracold atoms

Abstract

Ultracold atoms, which are gaseous atoms cooled to the quantum regime by laser cooling and evaporative cooling, provide an ideal platform to study quantum many-body systems. Especially, such atoms loaded into in periodic potential (optical lattice) created by a laser beam can be used to “simulate” fundamental condensed-matter models, such as the Hubbard model or the Heisenberg spin model. In this talk I explain ultracold atoms in optical lattices as a quantum simulator. Since the optical lattice systems are well separated from uncontrolled environments, they are also suitable systems to reveal non-equilibrium quantum dynamics. I will discuss possibilities of a quantum simulator for non-equilibrium phenomena, such as photo-induced phase transitions.
