Atomic Regional Superfluids in two-dimensional Moiré Time Crystals
Weijie Liang, Weiping Zhang, Keye Zhang
Moiré physics has transcended spatial dimensions, extending into synthetic domains and enabling novel quantum phenomena. We propose a theoretical model for a two-dimensional (2D) M…
Moiré Superradiance in Cavity Quantum Electrodynamics with Quantum Atom Gas
Lu Zhou, Zheng-Chun Li, Keye Zhang +3
As a novel platform for exploring exotic quantum phenomena, the moiré lattice has garnered significant interest in solid-state physics, photonics, and cold atom physics. While moir…
Bloch oscillations of spin-orbit-coupled cold atoms in an optical lattice and spin current generation
Wei Ji, Keye Zhang, Weiping Zhang +1
We study the Bloch oscillation dynamics of a spin-orbit-coupled cold atomic gas trapped inside a one-dimensioanl optical lattice. The eigenspectra of the system is identified as tw…
Cavity-induced switching between localized and extended states in a non-interacting Bose-Einstein condensate
Lu Zhou, Han Pu, Keye Zhang +2
We study an ultracold atom-cavity coupling system, which had been implemented in experiment to display weak light nonlinearity [S. Gupta \textit{et al}., Phys. Rev. Lett. \textbf{9…
Spin dynamics and domain formation of a spinor Bose-Einstein condensate in an optical cavity
Lu Zhou, Han Pu, Hong Y. Ling +2
We consider a ferromagnetic spin-1 Bose-Einstein condensate (BEC) dispersively coupled to a unidirectional ring cavity. We show that the ability of a cavity to modify, in a highly…
Efficient production of polar molecular Bose-Einstein condensates via an all-optical R-type atom-molecule adiabatic passage
Jing Qian, Lu Zhou, Keye Zhang +1
We propose a scheme of "-type" photoassociative adiabatic passage (PAP) to create polar molecular condensates from two different species of ultracold atoms. Due to the presence…
