Issue Date: | 22-Jan-2008 | Citation: | Wang, W.-G., Gong, J., Casati, G., Li, B. (2008-01-22). Entanglement-induced decoherence and energy eigenstates. Physical Review A - Atomic, Molecular, and Optical Physics 77 (1) : -. ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevA.77.012108 | Abstract: | 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 system-environment interaction and for a generic quantum chaotic system as environment, conditions are derived for energy eigenstates to be preferred states in the weak coupling regime. A simple model is introduced to numerically confirm our predictions. The results presented here may also help with understanding the dynamics of quantum entanglement generation in chaotic quantum systems. © 2008 The American Physical Society. | Source Title: | Physical Review A - Atomic, Molecular, and Optical Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/96497 | ISSN: | 10502947 | DOI: | 10.1103/PhysRevA.77.012108 |
