Quench dynamics in the Aubry-André-Harper model with \textit{p}-wave superconductivity
Qi-Bo Zeng, Shu Chen, Rong Lü
The Anderson localization phase transition in the Aubry-André-Harper (AAH) model with \textit{p}-wave superconducting (SC) pairing is numerically investigated by suddenly changing…
Topological edge states and pumping in a chain of coupled superconducting qubits
Xiu Gu, Shu Chen, Yu-xi Liu
Topological insulators have inspired the study with various quantum simulators. Exploiting the tunability of the qubit frequency and qubit-qubit coupling, we show that a supercondu…
Characterization of Lifshitz transitions in topological nodal line semimetals
Hui Jiang, Linhu Li, Jiangbin Gong +1
We introduce a two-band model of three-dimensional nodal line semimetals, the Fermi surface of which at half-filling may form various one-dimensional configurations of different to…
Dynamical topological invariant after a quantum quench
Chao Yang, Linhu Li, Shu Chen
We show how to define a dynamical topological invariant for general one-dimensional topological systems after a quantum quench. Focusing on two-band topological insulators, we demo…
Transition from nodal loop to nodal chain phase in a periodically modulated optical lattice
Chuanhao Yin, Linhu Li, Shu Chen
We propose to study the transition from a nodal loop to nodal chain phase in a tunable two-dimensional -flux lattice with periodical modulation potential. The Hamiltonian descri…
Characterization of topological phases of modified dimerized Kitaev chain via edge correlation functions
Yucheng Wang, Jian-Jian Miao, Shu Chen
We study analytically a modified dimerized Kitaev chain model under both periodic and open boundary conditions and determine its phase diagram by calculating the topological number…
