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…
Effective Dynamics for Weakly Interacting Bosons in an Iterated High-Density Thermodynamic Limit
Daniele Ferretti, Kalle Koskinen
We study the time evolution of weakly interacting Bose gases on a three-dimensional torus of arbitrary volume. The coupling constant is supposed to be inversely proportional to the…
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…
