Phase diagram of the disordered Bose-Hubbard model
V. Gurarie, L. Pollet, N. V. Prokof'ev +2
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, prov…
Suppression of the critical temperature for superfluidity near the Mott transition: validating a quantum simulator
S. Trotzky, L. Pollet, F. Gerbier +5
Ultracold atomic gases in optical lattices have proven to be a controllable, tunable and clean implementation of strongly interacting quantum many-body systems. An essential prospe…
Absence of a Direct Superfluid to Mott Insulator Transition in Disordered Bose Systems
L. Pollet, N. V. Prokof'ev, B. V. Svistunov +1
We prove the absence of a direct quantum phase transition between a superfluid and a Mott insulator in a bosonic system with generic, bounded disorder. We also prove compressibilit…
Binding of a 3He impurity to a screw dislocation in solid 4He
P. Corboz, L. Pollet, N. V. Prokof'ev +1
Using first-principle simulations for the probability density of finding a 3He atom in the vicinity of the screw dislocation in solid 4He, we determine the binding energy to the di…
Search for Deconfined Criticality: SU(2) Déjà Vu
A. B. Kuklov, M. Matsumoto, N. V. Prokof'ev +2
Monte Carlo simulations of the SU(2)-symmetric deconfined critical point action reveal strong violations of scale invariance for the deconfinement transition. We find compelling ev…
Superfluidity of Grain Boundaries in Solid Helium-4
L. Pollet, M. Boninsegni, A. B. Kuklov +3
By large-scale quantum Monte Carlo simulations we show that grain boundaries in Helium-4 crystals are generically superfluid at low temperature, with a transition temperature of th…
