Reply to Comment on "Quantum quasicrystals of spin-orbit coupled dipolar bosons''

In a recent Letter [Phys. Rev. Lett. 111, 185304 (2013)], we proposed a scheme for realizing quantum quasicrystals using spin-orbit coupled dipolar bosons. We remarked that these quantum quasicrystals have additional ``phason''-like modes compared with their classical counterparts. A recent comment by Lifshitz [arXiv:1312.1388] contests this claim. We argue here that our enumeration of gapless modes is indeed the physically relevant one; whether the additional modes are ``phasons'' is, however, a matter of definition.In a recent Letter [Phys.

Quantum Quasicrystals of Spin-Orbit-Coupled Dipolar Bosons

Sarang Gopalakrishnan, Ivar Martin, Eugene Demler

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 dipolar condensates, e.g., dysprosium, and discuss their symmetries and excitations.We study quasi-two-dimensional dipolar Bose gases in which the bosons experience a Rashba spin-orbit coupling.
