Topological bosonic Bogoliubov excitations with sublattice symmetry
Ling-Xia Guo, Liang-Liang Wan, Liu-Gang Si +2
Here we investigate the internal sublattice symmetry, and thus the enriched topological classification of bosonic Bogoliubov excitations of thermodynamically stable free-boson syst…
Out-of-Time-Order Correlation as a Witness for Topological Phase Transitions
Qian Bin, Liang-Liang Wan, Franco Nori +2
We propose a physical witness for dynamically detecting topological phase transitions (TPTs) via an experimentally observable out-of-time-order correlation (OTOC). The distinguisha…
Controllable nonlinearity in a dual-coupling optomechanical system under a weak-coupling regime
Gui-Lei Zhu, Xin-You Lü, Liang-Liang Wan +3
Strong quantum nonlinearity gives rise to many interesting quantum effects and has wide applications in quantum physics. Herewe investigate the quantum nonlinear effect of an optom…
