Quenched dynamics of the momentum distribution of the unitary Bose gas
Francesco Ancilotto, Maurizio Rossi, Luca Salasnich +1
We study the quenched dynamics of the momentum distribution of a unitary Bose gas under isotropic harmonic confinement within a time-dependent density functional approach based on…
Density functional theory of a trapped Bose gas with tunable scattering length: from weak-coupling to unitarity
Maurizio Rossi, Francesco Ancilotto, Luca Salasnich +1
We study an interacting Bose gas at T=0 under isotropic harmonic confinement within Density Functional Theory in the Local Density approximation. The energy density functional, whi…
Monte Carlo Simulations of the Unitary Bose Gas
Maurizio Rossi, Luca Salasnich, Francesco Ancilotto +1
We investigate the zero-temperature properties of a diluted homogeneous Bose gas made of particles interacting via a two-body square-well potential by perfor ming Monte Carlo s…
Supersolid structure and excitation spectrum of soft-core bosons in 3D
Francesco Ancilotto, Maurizio Rossi, Flavio Toigo
By means of a mean-field method, we have studied the zero temperature structure and excitation spectrum of a three-dimensional soft-core bosonic system for a value of the interacti…
Path-Integral Ground-State and Superfluid Hydrodynamics of a Bosonic Gas of Hard Spheres
Maurizio Rossi, Luca Salasnich
We study a bosonic gas of hard spheres by using of the exact zero-temperature Path-Integral Ground-State (PIGS) Monte Carlo method and the equations of superfluid hydrodynamics. Th…
