We perform quantum Monte Carlo simulations to study the 2D hard-core
Bose-Hubbard model in a random potential. Our motivation is to investigate the
effects of randomness on the Kosterlitz--Thouless (KT) transition. The chemical
potential is assume...

The hardcore-Bose-Hubbard model with random chemical potential is
investigated using quantum Monte Carlo simulation. We consider two cases of
random distribution of the chemical potential: a uniformly random distribution
and a correlated distribut...

The spin anisotropic exchange interaction is suggested to contribute
significantly to the abnormal upturn of the magnetic susceptibility in the
ZnCuTex(OH)TexClTex. The saturation of the magnetic susceptibility below 300
mK observed in the muon...

We report a method for determining the spatial dependence of the magnetic
exchange coupling, Tex, from magnetostriction measurements of a quantum
magnet. The organic Ni Tex system NiClTex-4SC(NHTex)Tex exhibits lattice
distortions in re...
