Rigorous derivation of the Efimov effect in a simple model
Davide Fermi, Daniele Ferretti, Alessandro Teta
We consider a system of three identical bosons in with two-body zero-range interactions and a three-body hard-core repulsion of a given radius . Using a quadrat…

Some Remarks on the Regularized Hamiltonian for Three Bosons with Contact Interactions
Daniele Ferretti, Alessandro Teta
We discuss some properties of a model Hamiltonian for a system of three bosons interacting via zero-range forces in three dimensions. In order to avoid the well known instability p…

Regularized Zero-Range Hamiltonian for a Bose Gas with an Impurity
Daniele Ferretti, Alessandro Teta
We study the Hamiltonian for a system of N identical bosons interacting with an impurity, i.e., a different particle, via zero-range forces in dimension three. It is well known tha…
