Fractional topological states of dipolar fermions in one-dimensional optical superlattices
Zhihao Xu, Linhu Li, Shu Chen
We study the properties of dipolar fermions trapped in one-dimensional bichromatic optical lattices and show the existence of fractional topological states in the presence of stron…
Geometric phase and quantum phase transition in an inhomogeneous periodic XY spin-1/2 model
Yu-Quan Ma, Shu Chen
The notion of geometric phase has been recently introduced to analyze the quantum phase transitions of many-body systems from the geometrical perspective. In this work, we study th…
Topological superconductor to Anderson localization transition in one-dimensional incommensurate lattices
Xiaoming Cai, Li-Jun Lang, Shu Chen +1
We study the competition of disorder and superconductivity for a one-dimensional p-wave superconductor in incommensurate potentials. With the increase in the strength of the incomm…
Wigner crystal versus Fermionization for one-dimensional Hubbard models with and without long-range interactions
Zhihao Xu, Linhu Li, Gao Xianlong +1
The ground state properties of Hubbard model with or without long-range interactions in the regime with strongly repulsive on-site interaction are investigated by means of the exac…
Majorana fermions in density modulated p-wave superconducting wires
Li-Jun Lang, Shu Chen
We study the p-wave superconducting wire with a periodically modulated chemical potential and show that the Majorana edge states are robust against the periodic modulation. We find…
Dynamical properties of hard-core anyons in one-dimensional optical lattices
Yajiang Hao, Shu Chen
We investigate the dynamical properties of anyons confined in one-dimensional optical lattice combined with a weak harmonic trap using the exact numerical method based on a general…
