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…
