Possibility of direct Mott insulator-to-superfluid transitions in weakly disordered boson systems

Sung Yong Park, Ji-Woo Lee, Min-Chul Cha +3

We study the zero-temperature phase transitions of a two-dimensional disordered boson Hubbard model at incommensurate boson densities. Via matrix diagonalization and quantum Monte…
