Topological invariant and cotranslational symmetry in strongly interacting multi-magnon systems
Xizhou Qin, Feng Mei, Yongguan Ke +2
It is still an outstanding challenge to characterize and understand the topological features of strongly interacting states such as bound-states in interacting quantum systems. Her…
Band-gap structure and chiral discrete solitons in optical lattices with artificial gauge fields
Qinzhou Ye, Xizhou Qin, Yongyao Li +3
We study three-leg-ladder optical lattices loaded with repulsive atomic Bose-Einstein condensates and subjected to artificial gauge fields. By employing the plane-wave analysis and…
Universal spatiotemporal dynamics of spontaneous superfluidity breakdown in the presence of synthetic gauge fields
Shuyuan Wu, Xizhou Qin, Jun Xu +1
According to the famous Kibble-Zurek mechanism (KZM), the universality of spontaneous defect generation in continuous phase transitions (CPTs) can be understood by the critical slo…
Asymmetric sequential Landau-Zener dynamics of Bose condensed atoms in a cavity
Jiahao Huang, Pu Gong, Xizhou Qin +2
We explore the asymmetric sequential Landau-Zener (LZ) dynamics in an ensemble of interacting Bose condensed two-level atoms coupled with a cavity field. Assuming the couplings bet…
Cluster Mean-Field Signature of Entanglement Entropy in Bosonic Superfluid-Insulator Transitions
Li Zhang, Xizhou Qin, Yongguan Ke +1
Entanglement entropy (EE), a fundamental conception in quantum information for characterizing entanglement, has been extensively employed to explore quantum phase transitions (QPTs…
Topological Phase Transitions and Thouless Pumping of Light in Photonic Waveguide Arrays
Yongguan Ke, Xizhou Qin, Feng Mei +3
Photonic waveguide arrays provide an excellent platform for simulating conventional topological systems, and they can also be employed for the study of novel topological phases in…
