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…
Witnessing topological Weyl semimetal phase in a minimal circuit-QED lattice
Feng Mei, Zheng-Yuan Xue, Dan-Wei Zhang +3
We present a feasible protocol to mimic topological Weyl semimetal phase in a small one-dimensional circuit-QED lattice. By modulating the photon hopping rates and on-site photon f…
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…
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…
