报告摘要(Abstract):
Ultracold bosons in two-legged latter systems are a fundamental model to understand the physics of larger systems. Here I will present our work on the ground state properties of such a system under the influence of an artificial staggered magnetic flux. I will show how to calculate the order parameters of the arising superfluid phases and find the full phase diagram, which is obtained analytically through the Landau theory of phase transitions and numerically through a Cluster-mean-field theory. Finally, I will show that the experimental signatures of the superfluids is given by the chiral currents.
