Non-Hermitian Hamiltonian beyond PT-symmetry for time-dependant SU(1,1) and SU(2) systems -- exact solution and geometric phase in pseudo-invariant theory
Nadjat Amaouche, Maroua Sekhri, Rahma Zerimeche +2
We investigate in this paper time-dependent non-Hermitian Hamiltonians, which consist respectively of SU(1,1) and SU(2) generators. The former Hamiltonian is PT symmetric but the l…
-symmetric non-Hermitian Hamiltonian and invariant operator in periodically driven system
Yan Gu, Xue-Min Bai, Xiao-Lei Hao +1
We study in this paper the time evolution of -symmetric non-Hermitian Hamiltonian consisting of periodically driven generators. A non-Hermitian invariant operator is…
Entanglement Dynamics for Two Spins in an Optical Cavity---Field Interaction Induced Decoherence and Coherence Revival
Xue-Min Bai, Chun-Ping Gao, Jun-Qi Li +2
We in this paper study quantum correlations for two neutral spin-particles coupled with a single-mode optical cavity through the usual magnetic interaction. Two-spin entangled stat…
Efficient spin-current injection in single-molecule magnet junctions
Haiqing Xie, Fuming Xu, Hujun Jiao +2
We study theoretically spin transport through a single-molecule magnet (SMM) in the sequential and cotunneling regimes, where the SMM is weakly coupled to one ferromagnetic and one…
Collective atomic-population-inversion and stimulated radiation for two-componentBose-Einstein condensate in an optical cavity
Xiuqin Zhao, Ni Liu, J-Q Liang
In this paper we investigate the ground-state properties and related quantum phase transitions for the two-component Bose-Einstein condensate in a single-mode optical cavity. Apart…
Dicke Phase Transition and Collapse of Superradiant Phase in Optomechanical Cavity with Arbitrary Number of Atoms
Xiuqin Zhao, Ni Liu, Xuemin Bai +1
We in this paper derive the analytical expressions of ground-state energy, average photon-number, and the atomic population by means of the spin-coherent-state variational method f…
