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 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…

Entanglement control in one-dimensional random XY spin chain
C. J. Shan, W. W. Cheng, T. K. Liu +2
The entanglement in one-dimensional random XY spin systems where the impurities of exchange couplings and the external magnetic fields are considered as random variables is investi…
