Composite Quantum phases in a system of tilted dipolar lattice bosons

ORAL

Abstract

Dipolar lattice bosons allow for the realization of novel quantum phases due to the long-range nature of the interaction and its inherent anisotropy. We utilize Path Integral Quantum Monte Carlo simulations, using a novel multi-worm extension to the Worm algorithm, to explore the phase diagram of hard-core dipolar bosons in a two-dimensional optical lattice as a function of the tilting angle. This setup allows for the formation of dipolar chains which can form a variety of composite insulating and superfluid phases.~
