Multipartite quantum correlation, spatially anisotropic coupling, and finite temperature effects in a triangular Ising system with tunable interactions
Jun Ren, Fang-Man Liu, Yan-Chao Li +3
We investigate multipartite quantum correlation (MQC), spatially anisotropic coupling, and finite temperature effects in a triangular Ising system with tunable interactions using t…
Correlations and dynamical quantum phase transitions in an interacting topological insulator
Wing Chi Yu, P. D. Sacramento, Yan Chao Li +1
Dynamical quantum phase transitions (DQPTs), which refer to the criticality in time of a quantum many-body system, have attracted much theoretical and experimental research interes…
Topological phase and lattice structures in spin chain models
Yan-Chao Li, Jing Zhang, Hai-Qing Lin
Finding new topological materials and understanding the physical essence of topology are crucial problems for researchers. We studied the topological property based on several prop…
Detection of topological phases by quasi-local operators
Wing Chi Yu, P. D. Sacramento, Yan Chao Li +2
It has been proposed recently by some of the authors that the quantum phase transition of a topological insulator like the SSH model may be detected by the eigenvalues and eigenvec…
Reduced density matrix and order parameters of a topological insulator
Wing Chi Yu, Yan Chao Li, P. D. Sacramento +1
It has been recently proposed that the reduced density matrix may be used to derive the order parameter of a condensed matter system. Here we propose order parameters for the phase…
Behavior of a Magnetic Impurity in Graphene in the Presence of a Vacancy
F. M. Hu, J. E. Gubernatis, Hai-Qing Lin +2
With quantum Monte Carlo methods, we investigate the consequences of placing a magnetic adatom adjacent to a vacancy in a graphene sheet. We find that instead of the adatom propert…
