Quantum quasicrystals and other exotic states of spin-orbit coupled dipolar bosons

ORAL

Abstract

We study dipolar Bose gases in which the bosons experience a Rashba spin-orbit coupling. We show that the degenerate dispersion minimum due to the spin-orbit coupling, combined with the long-range dipolar interaction, can stabilize a rich phase diagram including a number of exotic phases, such as a quantum quasicrystal [1] (in the quasi-2D limit) and a meron state [2] (in the 3D limit), as one tunes the strength of the dipolar interaction and the spin-orbit coupling. We discuss specific level schemes for exploring this phase diagram using ultracold dysprosium. [1] S. Gopalakrishnan, I. Martin, and E.A. Demler, Phys. Rev. Lett. 111, 185304 (2013) [2] R.M.
