Green’s function approach to the Bose–Hubbard model with disorder

Green’s function approach to the Bose–Hubbard model with disorder

We analyse the distinction between the three different ground states presented by a system of spinless bosons with short-range interactions submitted to a random potential using the disordered Bose–Hubbard model. The criteria for identifying the superfluid, the Mott-insulator, and the Bose-glass pha...
