Spin Hall mode in a trapped thermal Rashba gas
J. Armaitis, J. Ruseckas, H. T. C. Stoof +1
We theoretically investigate a two-dimensional harmonically-trapped gas of identical atoms with Rashba spin-orbit coupling and no interatomic interactions. In analogy with the spin…
Phase space curvature in spin-orbit coupled ultracold atom systems
J. Armaitis, J. Ruseckas, E. Anisimovas
We consider a system with spin-orbit coupling and derive equations of motion which include the effects of Berry curvatures. We apply these equations to investigate the dynamics of…
Omnidirectional spin Hall effect in a Weyl spin-orbit coupled atomic gas
J. Armaitis, J. Ruseckas, G. Juzeliūnas
We show that in the presence of a three-dimensional (Weyl) spin-orbit coupling, a transverse spin current is generated in response to either a constant spin-independent force or a…
Superfluidity and spin superfluidity in spinor Bose gases
J. Armaitis, R. A. Duine
We show that spinor Bose gases subject to a quadratic Zeeman effect exhibit coexisting superfluidity and spin superfluidity, and study the interplay between these two distinct type…
Hydrodynamic modes of partially condensed Bose mixtures
J. Armaitis, H. T. C. Stoof, R. A. Duine
We generalize the Landau-Khalatnikov hydrodynamic theory for superfluid helium to two-component (binary) Bose mixtures at arbitrary temperatures. In particular, we include the spin…
Quantum rotor model for a Bose-Einstein condensate of dipolar molecules
J. Armaitis, R. A. Duine, H. T. C. Stoof
We show that a Bose-Einstein condensate of heteronuclear molecules in the regime of small and static electric fields is described by a quantum rotor model for the macroscopic elect…
Magnetization relaxation and geometric forces in a Bose ferromagnet
J. Armaitis, H. T. C. Stoof, R. A. Duine
We construct the hydrodynamic theory for spin 1/2 Bose gases at arbitrary temperatures. This theory describes the coupling between the magnetization, and the normal and superfluid…
Polarons in Extremely Polarized Fermi Gases: The Strongly Interacting 6Li-40K Mixture
J. E. Baarsma, J. Armaitis, R. A. Duine +1
We study the extremely polarized two-component Fermi gas with a mass imbalance in the strongly interacting regime. Specifically we focus on the experimentally available mixture of…
