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…
Local quantum criticality in confined fermions on optical lattices
M. Rigol, A. Muramatsu, G. G. Batrouni +1
Using quantum Monte Carlo simulations, we show that the one-dimensional fermionic Hubbard model in a harmonic potential displays quantum critical behavior at the boundaries of a Mo…
Analytical and numerical study of hardcore bosons in two dimensions
K. Bernardet, G. G. Batrouni, J. -L. Meunier +3
We study various properties of bosons in two dimensions interacting only via onsite hardcore repulsion. In particular, we use the lattice spin-wave approximation to calculate the g…
Nature of the quantum phase transitions in the two-dimensional hardcore boson model
F. Hebert, G. G. Batrouni, R. T. Scalettar +3
We use two Quantum Monte Carlo algorithms to map out the phase diagram of the two-dimensional hardcore boson Hubbard model with near () and next near () neighbor repulsio…
