Superfluid mott insulation bose glass monte carlo simulation
2014/12/20
In a recent Letter [1] (see also [2]) the authors presented numerical evidence supporting an idea of a direct transition between the superfluid (SF) and Mott insulating (MI) phases in the disordered B...
The Fermi–Hubbard model at unitarity
Simulated rare appeal screw Fermi gas the thermodynamic functions
2014/12/20
We simulate the dilute attractive Fermi–Hubbard model in the unitarity regime using a diagrammatic determinant Monte Carlo (MC) algorithm with worm-type updates. We obtain the dependence of the critic...
Phase diagram and thermodynamics of the three-dimensional Bose-Hubbard model
Quantum monte carlo simulation 3 d space
2014/12/20
We report results of quantum Monte Carlo simulations of the Bose-Hubbard model in three dimensions. Critical parameters for the superfluid-to-Mott-insulator transition are determined with significantl...
Monte Carlo study of the two-dimensional Bose-Hubbard model
The most promising optical lattices ultracold gas condensate system quantum simulator
2014/12/19
One of the most promising applications of ultracold gases in optical lattices is the possibility to use them as quantum emulators of more complex condensed matter systems. We provide benchmark calcula...

Disordered phase diagram the three dimensional Bose - Hubbard model inclusions superfluids
2014/12/19
We establish the phase diagram of the disordered three-dimensional Bose-Hubbard model at unity filling which has been controversial for many years. The theorem of inclusions, proven by Pollet et al. [...
