Dipolar gases in triangular ladders — •Luis Santos — Institut für Theoretische Physik, Leibniz Universität Hannover

Experiments on dipolar quantum systems (magnetic atoms, polar molecules, Rydberg atoms) are opening interesting possibilities for the quantum simulation of spin models of interest in quantum magnetism. In particular, dipoles in triangular ladders (made with optical lattices or tweezer arrays) are characterized by the interplay between frustration and long-range interactions, allowing for the realization of intriguing phases and phase-transitions, such as a dipole-induced transition between a chiral-superfluid and a non-chiral two-component superfluid, or the realization of chiral and nematic spin phases [1]. In the spirit of the session, I will then discuss the possibilities of dipoles in triangular ladders in the context of existing proposals for anyon condensation [2].
