On Fermi's model for the scattering of a slow neutron from a bound proton
Domenico Finco, Raffaele Scandone, Alessandro Teta
We consider a model Hamiltonian, introduced by Fermi in 1936, describing a two-particle system made of a neutron and a harmonically bound proton, where the neutron-proton interacti…
A mathematical model for the Einstein-Podolsky-Rosen argument
Riccardo Adami, Luigi Barletti, Alessandro Teta
We study a nonrelativistic system made of two quantum particles constrained to move on a line and a spin located at a fixed point of the line. Initially the two particles are in a…
A Zero-Range Model for the Efimov Effect in the Born-Oppenheimer Approximation
G. Basti, D. Ferretti, A. Teta
In this note we discuss the Efimov effect emerging in a three-particle quantum system with zero-range interactions. In particular, we consider two non-interacting identical bosons…
Hamiltonians for Quantum Systems with Contact Interactions
Daniele Ferretti, Alessandro Teta
We discuss the problem of constructing self-adjoint and lower bounded Hamiltonians for a system of non-relativistic quantum particles in dimension three with contact (or zero…
Hamiltonian for a Bose gas with Contact Interactions
Daniele Ferretti, Alessandro Teta
We study the Hamiltonian for a three-dimensional Bose gas of spinless particles interacting via zero-range (also known as contact) interactions. Such interactions are en…
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…
