A quantum theory for a total system including a reference system
Wen-ge Wang
The standard formalism of quantum mechanics is extended to describe a total system including the reference system (RS), with respect to which the total system is described. The RS…
Stability of Fock states in a two-component Bose-Einstein condensate with a regular classical counterpart
Wen-ge Wang, Jie Liu, Baowen Li
We study the stability of a two-component Bose-Einstein condensate (BEC) in the parameter regime in which its classical counterpart has regular motion. The stability is characteriz…
Sensitivity of Quantum Motion to Perturbation in Triangle Map
Wen-ge Wang
We study quantum Loschmidt echo, or fidelity, in the triangle map whose classical counterpart has linear instability and weak chaos. Numerically, three regimes of fidelity decay ha…
Entanglement-induced Decoherence and Energy Eigenstates
Wen-ge Wang, Jiangbin Gong, G. Casati +1
Using recent results in the field of quantum chaos we derive explicit expressions for the time scale of decoherence induced by the system-environment entanglement. For a generic sy…
