In open quantum systems, topological edge states rapidly lose coherence, making them unsuitable for topological quantum computation and quantum memory. In this study, we demonstrate that topologically non-Hermitian Liouville-Majorana edge modes (LMEM

We carefully investigate the comprehensive impact of atom-cavity interaction and artificial magnetic fields on quantum phase transitions of anti-Jaynes-Cummings triangle model in the infinite frequency limit. We discover that ground states of the opt

We propose to protect fluxonium qubits that are away from half flux quantum against environmental noises, especially $1/f$ flux noise, by adopting a modulated flux with tunable-complex-amplitude. Using open-system Floquet theory, we derive a Lindblad

We propose a scheme to implement non-Abelian spin-orbital-angular-momentum (SOAM) coupling in spinor Bose–Einstein condensates using magnetic gradient coupling. For a spherical surface trap addressable using high-order Hermite–Gaussian beams, we

We consider a hybrid atom-optomechanical system consisting of a mechanical membrane inside an optical cavity and an atomic Bose-Einstein condensate outside the cavity. The condensate is confined in an optical lattice potential formed by a traveling l

We propose a general method to simulate arbitrary lattice models using a single degenerate cavity. Such a cavity supports a large number of degenerate optical modes with different angular momenta. Couplings between different optical modes can be read

We provide an explicit way to implement non-Abelian spin-orbital-angular-momentum (SOAM) coupling in spinor Bose-Einstein condensates using magnetic gradient coupling. For a spherical surface trap addressable using high-order Hermite-Gaussian beams,

We report the Bose-Einstein condensate (BEC) in the Bloch bands with off-diagonal periodic potential (ODPP), which simultaneously plays the role of spin-orbit coupling (SOC) and Zeeman field. This model can be realized using two independent Raman cou

The non-equilibrium dynamics of a one-dimensional (1D) topological system with 3rd-nearest-neighbor hopping has been investigated by analytical and numerical methods. An analytical form of topological defect density under the periodic boundary condit
