Quantum Monte Carlo simulation of a two-dimensional Bose gas
S. Pilati, J. Boronat, J. Casulleras +1
The equation of state of a homogeneous two-dimensional Bose gas is calculated using quantum Monte Carlo methods. The low-density universal behavior is investigated using different…
Equation of state of a Fermi gas in the BEC-BCS crossover: a quantum Monte Carlo study
G. E. Astrakharchik, J. Boronat, J. Casulleras +1
We calculate the equation of state of a two-component Fermi gas with attractive short-range interspecies interactions using the fixed-node diffusion Monte Carlo method. The interac…
Beyond Tonks-Girardeau: strongly correlated regime in quasi-one-dimensional Bose gases
G. E. Astrakharchik, J. Boronat, J. Casulleras +1
We consider a homogeneous 1D Bose gas with contact interactions and large attractive coupling constant. This system can be realized in tight waveguides by exploiting a confinement…
Higher order and infinite Trotter-number extrapolations in path integral Monte Carlo
L. Brualla, K. Sakkos, J. Boronat +1
Improvements beyond the primitive approximation in the path integral Monte Carlo method are explored both in a model problem and in real systems. Two different strategies are studi…
High momentum response of liquid 3He
F. Mazzanti, A. Polls, J. Boronat +1
A final-state-effects formalism suitable to analyze the high-momentum response of Fermi liquids is presented and used to study the dynamic structure function of liquid He. The…
