Systems

The MBL can exist in a variety of systems (1D).

Fermions

• Isolated weakly interacting (repulsive) electrons can have a finite temperature transition into an insulating state (conductivity exactly zero belows certain temperature, determined by interaction strength) ^[1]
• Strongly (repulsive) interacting fermions can have MBL state even at very high temperatures ^[2]
• attractive fermions have a transition between superconductivity and localization ^[3]

Spins

• Hisenberg model with random onsite fields for strong enough disorder shows localization for high energy states ^[4][5]

Bosons

• for repulsive bosons with weak dsiorder superfluidity persists ^[3]
• Tonks–Girardeau in random potential is localized, with no superfluidity down to zero T. ^[6]
