Bose-glass to Superfluid transition in the three-dimensional Bose-Hubbard Model
Peter Hitchcock, Erik S. Sorensen
We present a Monte Carlo study of the Bose-glass to superfluid transition in the three-dimensional Bose-Hubbard model. Simulations are performed on the classical (3 + 1) dimensiona…

Simulations of Disordered Bosons on Hyper-Cubic Lattices
Peter Hitchcock, Erik S. Sorensen
We address computational issues relevant to the study of disordered quantum mechanical systems at very low temperatures. As an example we consider the disordered Bose- Hubbard mode…

Dual Geometric Worm Algorithm for Two-Dimensional Discrete Classical Lattice Models
Peter Hitchcock, Erik S. Sørensen, Fabien Alet
We present a dual geometrical worm algorithm for two-dimensional Ising models. The existence of such dual algorithms was first pointed out by Prokof'ev and Svistunov \cite{Prokofev…
