Interaction induced topological Bogoliubov excitations in a spin-orbit coupled Bose-Einstein condensate
Guan-Hua Huang, Guang-Quan Luo, Zhigang Wu +1
We study topologically non-trivial excitations of a weakly interacting, spin-orbit coupled Bose-Einstein condensate in a two-dimensional square optical lattice, a system recently r…

Bosonic Topological Excitations from the Instability of a Quadratic Band Crossing
Guang-Quan Luo, Andreas Hemmerich, Zhi-Fang Xu
We investigate the interaction-driven instability of a quadratic band crossing arising for ultracold bosonic atoms loaded into a two-dimensional optical lattice. We consider the ca…
