Comment on “Phase Diagram of a Disordered Boson Hubbard Model in Two Dimensions”
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...
Commensurate Two-Component Bosons in an Optical Lattice: Ground State Phase Diagram
Bosons optical lattice superfluid quantum systems and quantum
2014/12/20
Two sorts of bosons in an optical lattice at commensurate filling factors can form five stable superfluid and insulating ground states with rich and nontrivial phase diagram. The structure of the grou...
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...

Quantum monte carlo simulation of low temperature isotopic mixture model
2014/12/19
We have studied by quantum Monte Carlo simulations the low temperature phase diagram of a mixture of isotopic, hard core bosons, described by the t-Jz-J⊥ model, with J⊥=αJz. The coexistence of superfl...

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. [...
Topological multicritical point in the phase diagram of the toric code model and three-dimensional lattice gauge Higgs model
Magnetic field the three dimensional Z2 higgs model fiction spatial direction monte carlo simulation model
2014/12/19
We construct a mapping between the two-dimensional toric code model in external magnetic fields, hz and hx, and the three-dimensional classical Ising system with plaquette interactions, which is equiv...

Confinement Chiral Symmetry Breaking QCD Spontaneous Symmetry Breaking
2011/1/7
I report the results of a series of works on the phase diagram of theories with a different number of colors and/or quarks in a different representation than in QCD. Similarities as well as difference...
Constraints for the QCD phase diagram from imaginary chemical potential
Constraints QCD phase diagram imaginary chemical potential
2011/1/13
We present unambiguous evidence from lattice simulations of Nf = 3 QCD for two tricritical
points in the (T,m) phase diagram at fixed imaginary m/T = ip /3 mod. 2p /3, one in the light
and one in th...
Phase diagram and critical endpoint for strongly-interacting quarks
Phase diagram critical endpoint strongly-interacting quarks
2011/1/14
We introduce a method based on the chiral susceptibility, which enables one to draw a phase diagram in the chemical-potential/temperature plane for strongly-interacting quarks whose interactions are d...

2010/4/12
With a recently developed time evolving block decimation (TEBD) algorithm, we numerically study the ground state quantum phase diagram of fermi mixtures with attractive inter-species interactions load...
