Boson localization and the superfluid-insulator transition
The phase diagrams and phase transitions of bosons with short-ranged repulsive interactions moving in periodic and/or random external potentials at zero temperature are investig...

We examine the metallic phase of the positionally disordered Anderson-Hubbard model as a prototype of a strongly correlated disordered metal. We find that the low-temperature th...
We base a scaling theory of localization on an expression for conductivity of a system of random elastic scatterers in terms of its scattering properties at a fixed energy. This...
