Bose-Einstein condensates with spin-orbit interaction.
In the spin-orbit regime, it is shown that a Bose gas is a spinor condensate made up of two non-orthogonal dressed spin states carrying different momenta, which shows a stripe structure with a contrast proportional to the overlap of the dressed states, which can be made very pronounced by adjusting the experimental parameters.
Universal properties of the ultracold Fermi gas
We present some general considerations on the properties of a two-component ultracold Fermi gas along the BEC-BCS crossover. It is shown that the interaction energy and the free energy can be written
Spin-orbit Coupling in Optical Lattices
In this review, we discuss the physics of spin-orbit coupled quantum gases in optical lattices. After reviewing some relevant experimental techniques, we introduce the basic theoretical model and
Universal Relations for a Fermi Gas Close to a p-Wave Interaction Resonance.
The effects of interaction near a p- wave resonance are captured by two contacts, which are related to the variation of energy with the p-wave scattering volume v and with the effective range R in two adiabatic theorems.
Stability condition of a strongly interacting boson-fermion mixture across an interspecies Feshbach resonance
We study the properties of dilute bosons immersed in a single-component Fermi sea across a broad boson-fermion Feshbach resonance. The stability of the mixture requires that the bare interaction
Production of Feshbach molecules induced by spin–orbit coupling in Fermi gases
The creation of Feshbach molecules by exploiting engineered spin–orbit coupling in a spin-polarized Fermi gas advances the experimental study of topological superfluidity in ultracold gases.
Evidence for universal relations describing a gas with p-wave interactions
In dilute gases, a set of universal relations, known as the contact relations, directly connects thermodynamics and microscopic properties. So far, they have been established only for interactions
Realization and detection of Weyl semimetals and the chiral anomaly in cold atomic systems
In this work, we describe a method to realize 3D Weyl semimetal by coupling multilayers of honeycomb optical lattice in the presence of a pair of Raman lasers. The Raman lasers render each isolated
