Diffusion Monte Carlo study of two-dimensional liquid He
S. Giorgini, J. Boronat, J. Casulleras
The ground-state properties of two-dimensional liquid He at zero temperature are studied by means of a quadratic diffusion Monte Carlo method. As interatomic potential we use a…

Bounds for the phonon-roton dispersion in superfluid 4He
J. Boronat, J. Casulleras, F. Dalfovo +2
The sum rule approach is used to derive upper bounds for the dispersion law of the elementary excitations of a Bose superfluid. Bounds are explicitly calculated for the ph…

Unbiased estimators in Quantum Monte Carlo methods: application to liquid He
J. Casulleras, J. Boronat
A Monte Carlo algorithm for computing quantum mechanical expectation values of coordinate operators in many body problems is presented. The algorithm, that relies on the forward wa…
