Superfluidity and Anderson localisation for a weakly interacting Bose gas in a quasiperiodic potential

Xiaolong Deng, Roberta Citro, Anna Minguzzi +1

Using exact diagonalisation and Density Matrix Renormalisation group (DMRG) approach, we analyse the transition to a localised state of a weakly interacting quasi-1D Bose gas subje…
