Anomalous decoherence effects in driven coupled quantum spin systems
Chuan-Jia Shan, Pan-Pan Wu, Wei-Wen Cheng +2
We discuss anomalous decoherence effects at zero and finite temperatures in driven coupled quantum spin systems. By numerical simulations of the quantum master equation, it is foun…
A Question: Quantum Critical Phenomena in XY Spin-Chain Systems With Dzyaloshinskii-Moriya Interactions
Chuan-Jia Shan, Wei-Wen Cheng, Ji-Bing Liu +3
Jordan-Wigner transformation and Bogolyubov transformation are the main steps of the diagonalization of Hamiltonian and paly an important role in the statistical mechanics calculat…
The controlled teleportation of an arbitrary two-atom entangled state in driven cavity QED
Chuan-Jia Shan, Ji-Bing Liu, Tang-Kun Liu +2
In this paper, we propose a scheme for the controlled teleportation of an arbitrary two-atom entangled state in driven cavity…
Sudden death, birth and stable entanglement in a two-qubit Heisenberg XY spin chain
Chuan-Jia Shan, Wei-Wen Cheng, Tang-Kun Liu +2
Taking the decoherence effect due to population relaxation into account, we investigate the entanglement properties for two qubits in the Heisenberg XY interaction and subject to a…
Entanglement dynamics and Bell Violations of two atoms in Tavis-Cummings model with phase decoherence
C. J. Shan, W. W. Cheng, T. K. Liu +2
Considering the dipole-dipole coupling intensity between two atoms and the field in the Fock state, the entanglement dynamics between two atoms that are initially entangled in the…
Entanglement and quantum phase transition in alternating XY spin chain with next-nearest neighbour interactions
C. J. Shan, W. W. Cheng, T. K. Liu +2
By using the method of density-matrix renormalization-group to solve the different spin-spin correlation functions, the nearest-neighbouring entanglement(NNE) and next-nearest-neig…
