Entanglement Entropy of Free Fermions in Timelike Slices
Bowei Liu, Hao Chen, Biao Lian
We define the entanglement entropy of free fermion quantum states in an arbitrary spacetime slice of a discrete set of points, and particularly investigate timelike (causal) slices…

Monte Carlo study of duality and the Berezinskii-Kosterlitz-Thouless phase transitions of the two-dimensional -state clock model in flow representations
Hao Chen, Pengcheng Hou, Sheng Fang +1
The two-dimensional -state clock model for undergoes two Berezinskii-Kosterlitz-Thouless (BKT) phase transitions as temperature decreases. Here we report an extensive…

A novel exact solution to transmission problem of electron wave in a nonlinear Kronig-Penney superlattice
Chao Kong, Kuo Hai, Jintao Tan +2
Nonlinear Kronig-Penney model has been frequently employed to study transmission problem of electron wave in a nonlinear electrified chain or in a doped semiconductor superlattice.…
