Destruction of diagonal and off-diagonal long range order by disorder in two-dimensional hard core boson systems
K. Bernardet, G. G. Batrouni, M. Troyer +1
We use quantum Monte Carlo simulations to study the effect of disorder, in the form of a disordered chemical potential, on the phase diagram of the hard core bosonic Hubbard model…

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…
