Interacting classical dimers on the square lattice
Fabien Alet, Jesper Lykke Jacobsen, Gregoire Misguich +3
We study a model of close-packed dimers on the square lattice with a nearest neighbor interaction between parallel dimers. This model corresponds to the classical limit of quantum…
Supersolids versus phase separation in two-dimensional lattice bosons
Pinaki Sengupta, Leonid P. Pryadko, Fabien Alet +2
We study the nature of the ground state of the strongly-coupled two dimensional extended boson Hubbard model on a square lattice. We demonstrate that strong but finite on-site inte…
Quantum Monte Carlo simulations of confined bosonic atoms in optical lattices
Stefan Wessel, Fabien Alet, Matthias Troyer +1
We study properties of ultra-cold bosonic atoms in one, two and three dimensional optical lattices by large scale quantum Monte Carlo simulations of the Bose Hubbard model in parab…
Generalized Directed Loop Method for Quantum Monte Carlo Simulations
Fabien Alet, Stefan Wessel, Matthias Troyer
Efficient quantum Monte Carlo update schemes called directed loops have recently been proposed, which improve the efficiency of simulations of quantum lattice models. We propose to…
Non-local updates for quantum Monte Carlo simulations
M. Troyer, F. Alet, S. Trebst +1
We review the development of update schemes for quantum lattice models simulated using world line quantum Monte Carlo algorithms. Starting from the Suzuki-Trotter mapping we discus…
