Breakdown of bosonic Thouless pump due to interaction in a quasiperiodic lattice

Suman Mondal, Emmanuel Gottlob, Fabian Heidrich-Meisner +1

We investigate the effect of inter-particle interaction on the quantized Thouless pump in the bosonic quasiperiodic Aubry-Andr{é} model and find that the quantization of the pumpe…
