Phase diagram of a generalized off-diagonal Aubry-André model with p-wave pairing
Tong Liu, Pei Wang, Shu Chen +1
Off-diagonal Aubry-André (AA) model has recently attracted a great deal of attention as they provide condensed matter realization of topological phases. We numerically study a gene…
Zeros of Loschmidt echo in the presence of Anderson localization
Honghao Yin, Shu Chen, Gao Xianlong +1
We study the Loschmidt echo and the dynamical free energy of the Anderson model after a quench of the disorder strength. If the initial state is extended and the eigenstates of the…
Topological Phase Transition and Charge Pumping in a One-Dimensional Periodically Driven Optical Lattice
Zhihao Xu, Yunbo Zhang, Shu Chen
Experimental realizations of topological quantum systems and detections of topological invariants in ultracold atomic systems have been a greatly attractive topic. In this work, we…
Spectroscopy and spin dynamics for strongly interacting few spinor bosons in one-dimensional traps
Yanxia Liu, Shu Chen, Yunbo Zhang
We consider a one-dimensional trapped gas of strongly interacting few spin-1 atoms which can be described by an effective spin chain Hamiltonian. Away from the SU(3) integrable poi…
Exact ordering of energy levels for one-dimensional interacting Fermi gases with symmetry
Lei Pan, Yanxia Liu, Haiping Hu +2
Based on the exact solution of one-dimensional Fermi gas systems with symmetry in a hard wall, we demonstrate that we are able to sort the ordering of the lowest energy eig…
