Landauer's princple for Fermionic field in one dimensional bag
Yu-Song Cao, YanXia Liu, Rong Zhang
We study the Landauer's principle of an Unruh-DeWitt detector linearly coupled to Dirac field in dimensional cavity. When the initial state of the field is vacuum, we obtai…
Quantum Quench dynamics in XY spin chain with ferromagnetic and antiferromagnetic interactions
Zhe Wang, Pan-Pan Fang, Yu-Liang Xu +4
In this manuscript we investigate the one-dimensional anisotropic XY model with ferromagnetic and antiferromagnetic interactions, which gives more interesting phase diagrams and dy…
Dynamics of entanglement in the one-dimensional anisotropic XXZ model
Han Zhang, Yu-Liang Xu, Rong-Tao Zhang +4
The dynamics of entanglement in the one-dimensional spin-1/2 anisotropic XXZ model is studied using the quantum renormalization-group method. We obtain the analytical expression of…
Localized State in a Two-Dimensional Quantum Walk on a Disordered Lattice
Peng Xue, Rong Zhang, Zhihao Bian +3
We realize a pair of simultaneous ten-step one-dimensional quantum walks with two walkers sharing coins, which we prove is analogous to the ten-step two-dimensional quantum walk wi…
