Study of Kosterlitz-Thouless transition of Bose systems governed by a random potential using quantum Monte Carlo simulations
Hiroki Kuroyanagi, Mitsuaki Tsukamoto, Makoto Tsubota
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 Kos…
Quantum Monte Carlo simulations for the Bose-Hubbard model with random chemical potential; localized Bose-Einstein condensation without superfluidity
Mitsuaki Tsukamoto, Makoto Tsubota
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 po…
Using magnetostriction to measure the spin-spin correlation function and magnetoelastic coupling in the quantum magnet NiCl-4SC(NH)
V. S. Zapf, V. F. Correa, P. Sengupta +9
We report a method for determining the spatial dependence of the magnetic exchange coupling, , from magnetostriction measurements of a quantum magnet. The organic Ni …
Magnetic Excitations in the Spin-1 Anisotropic Heisenberg Antiferromagnetic Chain System NiCl-4SC(NH)
S. A. Zvyagin, J. Wosnitza, C. D. Batista +7
NiCl-4SC(NH) (DTN) is a quantum S=1 chain system with strong easy-pane anisotropy and a new candidate for the Bose-Einstein condensation of the spin degrees of freedom.…
