Title: Bosons in an optical lattice with a synthetic magnetic field
Abstract: Ultracold atoms in a optical lattice have been a particularly important field to study a wide range of fundamental problems in condensed matter physics. Recently, there have been some proposals to "synthesize" a magnetic field to the lattice systems, which provides a plausible route to realize quantum correlated phases of cold atoms such as quantum Hall states. In this talk, we present finite temperature phase structures of hard-core bosons in a two-dimensional optical lattice subject to a synthetic magnetic field.
