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…

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 magnon bound-states in periodically modulated Heisenberg XXZ chains
Xizhou Qin, Feng Mei, Yongguan Ke +2
Strongly interacting topological states in multi-particle quantum systems pose great challenges to both theory and experiment. Recently, bound states of elementary spin waves (magn…
