Far from equilibrium quantum magnetism with ultracold polar molecules
Dr. Salvatore Manmana (Universität Göttingen)

Recent theoretical progress has indicated how to emulate tuneable models of quantum magnetism with ultracold polar molecules. In this talk, I am going to discuss the underlying ideas and the effective model obtained from this ansatz, which is a generalised t-J model with long-range interactions. The simplest realization in 1D is a t-J_perp model, in which only interactions of the XY-type survive. Using the DMRG, I discuss the effect of the absence of the original SU(2) symmetry of the t-J-model on the phase diagram, in particular in superconducting phases. In the second part of my talk, I will discuss features of these quantum simulators when going out-of-equilibrium.
