Topological Higgs Amplitude Modes in Strongly Interacting Superfluids
Junsen Wang, Youjin Deng, Wei Zheng
By studying the 2-dimensional Su-Schrieffer-Heeger-Bose-Hubbard model, we show the existence of topological Higgs amplitude modes in the strongly interacting superfluid phase. Usin…

Pseudo-time-reversal-symmetry-protected topological Bogoliubov excitations of Bose-Einstein condensates in optical lattices
Junsen Wang, Wei Zheng, Youjin Deng
Bogoliubov excitations of Bose-Einstein condensates in optical lattices may possess band topology in analogous to topological insulators in class AII of fermions. Using the languag…
