A series of (Li0.8Fe0.2)OHFeSe1−xSx (0 x 1) samples were successfully synthesized via hydrothermal reactionmethod and the phase diagram is established.Magnetic susceptibility suggests that a...
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...
