On the Melting of Bosonic Stripes
Guido Schmid, Matthias Troyer
We use quantum Monte Carlo simulations to determine the finite temperature phase diagram and to investigate the thermal and quantum melting of stripe phases in a two-dimensional ha…

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…
