Global quantum discord in infinite quantum spin chains
Zhao-Yu Sun, Yan-E Liao, Bin Guo +10
In this paper, we study global quantum discord (GQD) in infinite-size spin chains. For this purpose, in the framework of matrix product states (MPSs), we propose an effective proce…

Multi-partite quantum nonlocality and Bell-type inequalities in an infinite-order quantum phase transition of the one-dimensional spin-1/2 XXZ chain
Zhao-Yu Sun, Shuang Liu, Hai-Lin Huang +7
In this paper, combined with infinite time-evolving block decimation (iTEBD) algorithm and Bell-type inequalities, we investigate multi-partite quantum nonlocality in an infinite o…
