Interplay of nonreciprocity and nonlinearity on mean-field energy and dynamics of a Bose-Einstein condensate in a double-well potential
Yi-Piao Wu, Guo-Qing Zhang, Cai-Xia Zhang +2
We investigate the mean-field energy spectrum and dynamics in a Bose-Einstein condensate in a double-well potential with non-Hermiticity from the nonreciprocal hopping, and show th…
Induced entanglement entropy of harmonic oscillators in noncommutative phase space
Bing-Sheng Lin, Jian Xu, Tai-Hua Heng
We study the entanglement entropy of harmonic oscillators in noncommutative phase space. We propose a new definition of quantum Rényi entropy based on Wigner functions in noncommut…
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…
Interferometric detection of Chern numbers in topological optical lattices
Jian Xu
Topological states of matter emergent as a new type of quantum phases, which can be distinguished by their associated topological invariants, e.g., Chern numbers. Currently, there…
Violation of Bell inequality in perfect translation invariant systems
Zhao-Yu Sun, Yu-Ying Wu, Hai-Lin Huang +2
Bell inequalities and nonlocality have been widely studied in one-dimensional quantum systems. As a kind of quantum correlation, it is expected that bipartite nonlocaity should be…
