From few to many bosons inside the unitary window: a transition between universal to non-universal behavior
A. Kievsky, A. Polls, B. Juliá-Díaz +2
Universal behaviour in few-bosons systems close to the unitary limit, where two bosons become unbound, has been intensively investigated in recent years both experimentally and the…
Bosonic drops with two- and three-body interactions close to the unitary limit
A. Kievsky, A. Polls, B. Julia-Diaz +2
When the binding energy of a two-body system goes to zero the two-body system shows a continuous scaling invariance governed by the large value of the scattering length. In the cas…
Saturation properties of helium drops from a Leading Order description
A. Kievsky, A. Polls, B. Juliá-Díaz +1
Saturation properties are directly linked to the short-range scale of the two-body interaction of the particles. The case of helium is particular, from one hand the two-body potent…
-boson spectrum from a Discrete Scale Invariance
A. Kievsky, N. K. Timofeyuk, M. Gattobigio
We present the analysis of the -boson spectrum computed using a soft two-body potential the strength of which has been varied in order to cover an extended range of positive and…
Efimov spectrum in bosonic systems with increasing number of particles
A. Kievsky, M. Gattobigio, N. K. Timofeyuk
It is well-known that three-boson systems show the Efimov effect when the two-body scattering length is large with respect to the range of the two-body interaction. This effect…
