Contac interactions, Gamma convergence in Electrodynamics and the (Nelson) Polaron

Gianfausto Dell'Antonio

The Polaron is the quantum of a "Polarization" field originated by the "contact" interaction [D1][D2] of a massive polarizable particle with a photon. We prove that this process pr…

Contact interactions in Q.M. Gamma convergence and Bose-Einstein condensation

Gianfausto Dell'Antonio

We describe \emph{zero range} (contact) interactions, weak and strong. Strong contact leads to the Efimov effect in Low Energy Nuclear Physics, weak contact leads to Bose-Einstein…

Zero range interactions in d=3 and d=2 revisited

Gianfausto Dell'Antonio

This paper has a two-fold purpose: 1) to clarify the difference between contact and weak-contact interactions (called point interactions in [A] in the case ) in three dimensio…

Zero range (contact) interactions conspire to produce Efimov trimers and quadrimers

Gianfausto Dell'Antonio

We introduce \emph{contact (zero range) interactions } , a special class of self-adjoint extensions of the N-body Schrödinger free hamiltonian restricted to functions with s…

N-body problem with contact interactions

Gianfausto Dell'Antonio

We introduce \emph{contact interactions hamiltonians} (self-adjointoperators defined by boundary conditions) between massive particles in , . We prove that they…

The boundedness of wave operators for the three-dimensional multi-centre point interaction

Gianfausto Dell'Antonio, Alessandro Michelangeli, Raffaele Scandone +1

We prove that, for arbitrary centres and strengths, the wave operators for three dimensional Schrödinger operators with multi-centre local point interactions are bounded in $L^p(\m…
