Spin-orbit-coupling-induced phase separation in trapped Bose gases
Zhiqian Gui, Zhenming Zhang, Jin Su +2
In a trapped spin-1/2 Bose-Einstein condensate with miscible interactions, a two-dimensional spin-orbit coupling can introduce an unconventional spatial separation between the two…
Quantum phases in spin-orbit-coupled Floquet spinor Bose gases
Yani Zhang, Yuanyuan Chen, Hao Lyu +1
We propose a spin-orbit-coupled Floquet spinor Bose-Einstein condensate (BEC) which can be implemented by Floquet engineering of a quadratic Zeeman field. The Floquet spinor BEC ha…
Elementary excitations in a spin-orbit-coupled spin-1 Bose-Einstein condensate
Yuanyuan Chen, Hao Lyu, Yong Xu +1
While a spin-orbit-coupled spin-1 Bose-Einstein condensate has been experimentally observed, its elementary excitations remain unclear in the stripe phase. Here, we systematically…
Detection of roton and phonon excitations in a spin-orbit coupled Bose-Einstein condensate with a moving barrier
Hao Lyu, Yongping Zhang, Thomas Busch
We propose to detect phonon and roton excitations in a two-dimensional Bose-Einstein condensate with Raman-induced spin-orbit coupling by perturbing the atomic cloud with a weak ba…
Self-interfering dynamics in Bose-Einstein condensates with engineered dispersions
Jin Su, Hao Lyu, Yongping Zhang
Optical lattice and spin-orbit coupling are typical experimental approaches to engineer dispersion. We reveal a self-interfering dynamics in a noninteracting Bose-Einstein condensa…
Creating moving gap solitons in spin-orbit-coupled Bose-Einstein condensates
Jin Su, Hao Lyu, Yuanyuan Chen +1
A simple and efficient method to create gap solitons is proposed in a spin-orbit-coupled spin-1 Bose-Einstein condensate. We find that a free expansion along the spin-orbit couplin…
Spin-orbit-coupling-assisted roton softening and superstripes in a Rydberg-dressed Bose-Einstein Condensate
Hao Lyu, Yongping Zhang
Rotons can exist in ultracold atomic gases either with long-range interactions or with spin-orbitcoupled dispersions. We find that two different kinds of rotons coexist in a joint…
