Schrödinger operators with multiple Aharonov-Bohm fluxes
Michele Correggi, Davide Fermi
We study the Schrödinger operator describing a two-dimensional quantum particle moving in presence of Aharonov-Bohm magnetic fluxes. We classify all the self-adjo…
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…
Quadratic forms for Aharonov-Bohm Hamiltonians
Davide Fermi
We consider a charged quantum particle immersed in an axial magnetic field, comprising a local Aharonov-Bohm singularity and a regular perturbation. Quadratic form techniques are u…
Periodic striped states in Ising models with dipolar interactions
Davide Fermi, Alessandro Giuliani
We review the problem of determining the ground states of 2D Ising models with nearest neighbor ferromagnetic and dipolar interactions, and prove a new result supporting the conjec…
A note on "Algebraic approach to Casimir force between two -like potentials" (K. Ziemian, Ann. Henri Poincaré, Online First, 2021)
Davide Fermi, Livio Pizzocchero
We comment on the recent work [1], and on its relations with our papers [2,3] cited therein. In particular we show that, contrarily to what stated in [1], the Casimir energy densit…
Vacuum polarization with zero-range potentials on a hyperplane
Davide Fermi
The quantum vacuum fluctuations of a neutral scalar field induced by background zero-range potentials concentrated on a flat hyperplane of co-dimension in -dimensional M…
