Universal tetramer limit-cycle at the unitarity limit
Tobias Frederico, Mario Gattobigio
We demonstrate that a four-boson limit-cycle independent of the Efimov one appears in Hamiltonian systems at the unitary limit. The model interaction contains two-, three- and four…
Efimov Physics in small bosonic clusters
M. Gattobigio, A. Kievsky, M. Viviani
We study small clusters of bosons, , characterized by a resonant interaction. Firstly, we use a soft-gaussian interaction that reproduces the values of the dimer bindi…
Energy spectra of small bosonic clusters having a large two-body scattering length
M. Gattobigio, A. Kievsky, M. Viviani
In this work we investigate small clusters of bosons using the hyperspherical harmonic basis. We consider systems with particles interacting through a soft inter-part…
Six-bodies calculations using the Hyperspherical Harmonics method
M. Gattobigio, A. Kievsky, M. Viviani
In this work we show results for light nuclear systems and small clusters of helium atoms using the hyperspherical harmonics basis. We use the basis without previous symmetrization…
