Dynamic process and Uhlmann process: Incompatibility and dynamic phase of mixed quantum states
Hao Guo, Xu-Yang Hou, Yan He +1
While a pure quantum state may accumulate both the Berry phase and dynamic phase as it undergoes a cyclic path in the parameter space, the situation is more complicated when mixed…
Dynamics of 2D topological quadrupole insulator and Chern insulator induced by real-space topological changes
Yan He, Chih-Chun Chien
The dynamics of two-dimensional (2D) topological quadrupole insulator (TQI) and Chern insulator (CI) after the real-space configuration is transformed from a cylinder or Mobius str…
Mass-imbalance induced structures of binary atomic mixtures in box potentials
Bishal Parajuli, Daniel Pecak, Chih-Chun Chien
We consider the ground states of binary atomic boson-boson and fermion-fermion mixtures confined in one-dimensional box potentials by simulating the systems using few-body models w…
Three dimensional two-band Floquet topological insulator with index
Yan He, Chih-Chun Chien
We present a class of three dimensional (3D) two-band Floquet topological insulators constructed from two-dimensional Floquet topological insulators with a topological index. I…
