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…
Order parameter conditions from mutual information and symmetry conditions
Ivan Arraut, Wing Chi Yu
The mutual information method has demonstrated to be very useful for deriving the potential order parameter of a system. Although the method suggests some constraints which help to…
Quantum phase transitions in the spin-1 Kitaev-Heisenberg chain
Wen-Long You, Gaoyong Sun, Jie Ren +2
Recently, it has been proposed that higher-spin analogues of the Kitaev interactions may also occur in a number of materials with strong Hund's and spin-orbit coupling. In th…
Stabilization of antiferromagnetism in 1T-FeTaS
Q. Niu, W. Zhang, Y. T. Chan +9
1T-TaS is a prototypical charge-density-wave (CDW) system with a Mott insulating ground state. Usually, a Mott insulator is accompanied by an antiferromagnetic state. However,…
Nonsaturating large magnetoresistance in the high carrier density nonsymmorphic metal CrP
Q. Niu, W. C. Yu, E. I. Paredes Aulestia +10
The band structure of high carrier density metal CrP features an interesting crossing at the Y point of the Brillouin zone. The crossing, which is protected by the nonsymmorphic sy…
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…
