Quantum critical behavior of a three-dimensional superfluid-Mott glass transition
Jack Crewse, Cameron Lerch, Thomas Vojta
The superfluid to insulator quantum phase transition of a three-dimensional particle-hole symmetric system of disordered bosons is studied. To this end, a site-diluted quantum roto…

Quantum critical behavior of the superfluid-Mott glass transition
Thomas Vojta, Jack Crewse, Martin Puschmann +2
We investigate the zero-temperature superfluid to insulator transitions in a diluted two-dimensional quantum rotor model with particle-hole symmetry. We map the Hamiltonian onto a…
