Impurity in a Bose-Einstein condensate: study of the attractive and repulsive branch using quantum Monte-Carlo methods
L. A. Peña Ardila, S. Giorgini
We investigate the properties of an impurity immersed in a dilute Bose gas at zero temperature using quantum Monte-Carlo methods. The interactions between bosons are modeled by a h…

Variational Monte Carlo study of soliton excitations in hard-sphere Bose gases
Riccardo Rota, Stefano Giorgini
By using a full many-body approach, we calculate the excitation energy, the effective mass and the density profile of soliton states in a three dimensional Bose gas of hard spheres…
