Feynman relation of Bose-Einstein condensates with spin-orbit coupling

Pei-Song He, Renyuan Liao, Wu‐Ming Liu

We find that the Feynman relation of Bose-Einstein condensates with spin-orbit coupling, which relates the energy of excitations, the static structure factor in condensed phase, and the dispersion of free bosons, is not satisfied in the whole momentum space. The dispersion is highly anisotropic and more divergent in the infrared limit compared to that without spin-orbit coupling because of spontaneous breaking of the O(2) symmetry of the ground state. And the dispersion also exhibits time reversal asymmetry for plane-wave condensates, which is condensed on a momentum with a finite value. We also find that larger spin-orbit coupling makes the excitations out of condensates more coherent.

Experimental realization of a long-lived striped Bose-Einstein condensate induced by momentum-space hopping

Thomas M. Bersano, Junpeng Hou, Sean M. Mossman +5 more

The search for supersolidlike phases has attracted great attention in the fields of condensed matter and ultracold atom physics. Here, we experimentally demonstrate a route for realizing a superfluid stripe phase in a spin-orbit coupled Bose-Einstein condensate by employing a weak optical lattice to induce momentum-space hopping between two spin-orbit band minima. We characterize the striped ground state as a function of lattice coupling strength and spin-orbit detuning and find good agreement with mean-field simulations. We observe coherent Rabi oscillations in momentum space between two band minima and demonstrate a long lifetime of the ground state. Our work offers an exciting and stable experimental platform for exploring superfluid stripe phases and their exotic excitations, which may shed light on the properties of supersolidlike states.
