Multiparticle Wannier states and Thouless pumping of interacting bosons

Ke, Yongguan; Qin, Xizhou; Kivshar, Yuri; Lee, C.-H.


The study of topological effects in physics is a hot area of research, and only recently have researchers been able to address the important issues of topological properties of interacting quantum systems. But it is still a great challenge to describe multiparticle and interaction effects. Here, we introduce the multiparticle Wannier states for interacting systems with cotranslational symmetry, which provide an orthogonal basis for constructing effective Hamiltonians for the isolated bands. We...[Show more]
