Magnetocaloric effect in two-dimensional spin-1/2 antiferromagnets
A. Honecker, S. Wessel
The magnetocaloric effect is studied at the transition to saturation in the antiferromagnetic spin-1/2 Heisenberg model on the simplest two-dimensional lattices, namely the square…
Supersolid hardcore bosons on the triangular lattice
Stefan Wessel, Matthias Troyer
We determine the phase diagram of hardcore bosons on a triangular lattice with nearest neighbor repulsion, paying special attention to the stability of the supersolid phase. Simila…
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…
Thermodynamic properties of ferromagnetic mixed-spin chain systems
Noboru Fukushima, Andreas Honecker, Stefan Wessel +1
Using a combination of high-temperature series expansion, exact diagonalization and quantum Monte Carlo, we perform a complementary analysis of the thermodynamic properties of quas…
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…
