for the discovery of the MBL phase.
We wish to go beyond the conventional paradigm and ask whether randomness is indeed an essential ingredient
in achieving generic non-ergodic interacting phases.
We proposed the idea that the essential ingredient for MBL is localization, which does not necessarily
mean disorder. We analyze the spectral and the dynamical properties of one-dimensional interacting fermions and spins in the presence of both disorder and linear potential. We show that by considering these two different localizing mechanisms, i.e., disorder and linear fields, one may construct a two-dimensional phase diagram which hosts a connected non-ergodic (MBL) phase.
