Decoherence and localization in tunneling process under influence of one external degree of freedom
Quanlin Jie, Bambi Hu, Guangjong Dong
We investigate numerically the tunneling effect under influence of another particle in a double well system. Such influence from only one degree of freedom makes decoherence and qu…
Entanglement as a signature of quantum chaos
Xiaoguang Wang, Shohini Ghose, Barry C Sanders +1
We explore the dynamics of entanglement in classically chaotic systems by considering a multiqubit system that behaves collectively as a spin system obeying the dynamics of the qua…
Mode entanglement of electrons in the one-dimensional Frenkel-Kontorova model
Xiaoguang Wang, Haibin Li, Bambi Hu
We study the mode entanglement in the one-dimensional Frenkel-Kontorova model, and found that behaviors of quantum entanglement are distinct before and after the transition by brea…
Bipartite entanglement and localization of one-particle states
Haibin Li, Xiaoguang Wang, Bambi Hu
We study bipartite entanglement in a general one-particle state, and find that the linear entropy, quantifying the bipartite entanglement, is directly connected to the paricitpatio…
Fejer average and the short term behaviors of a wave packet in infinite square well
Quan-Hui Liu, Wei-Hong Qi, Li-Ping Fu +1
The first two period behaviors of a quantum wave packet in an infinite square well potential is studied. First, the short term behavior of expectation value of a quantity on an equ…
Nonadiabatic geometric phase for the cyclic evolution of a time-dependent Hamiltonian system
Jie Liu, Bambi Hu, Baowen Li
The geometric phases of the cyclic states of a generalized harmonic oscillator with nonadiabatic time-periodic parameters are discussed in the framework of squeezed state. It is sh…
