@article{Gopalakrishnan2013QuantumQO, title={Quantum quasicrystals of spin-orbit-coupled dipolar bosons.}, author={Sarang Gopalakrishnan and Ivar Martin and Eugene A. Demler}, journal={Physical review letters}, year={2013}, volume={111 18}, pages={ 185304 } }
We study quasi-two-dimensional 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 number of quantum crystalline and quasicrystalline ground states. Coupling the bosons to a fermionic species can further stabilize these phases. We estimate that the crystalline and quasicrystalline phases should be detectable in realistic…

It is demonstrated that the combined effects of spin-orbit coupling and interatomic soft-core long-range interaction can induce an exotic supersolid phase in which the chiral symmetry is broken with spontaneous emergence of circulating particle current.

It is shown that investigating SO coupling in cold atom systems can enrich the understanding of basic phenomena such as superfluidity, provide a good platform for simulating condensed matter states such as topological superfluids and result in novel quantum systems such as SO coupled unitary Fermi gas and high spin quantum gases.
