Vacuum and thermal fluctuations of a scalar field with point interactions
Davide Fermi, Marco Gurgoglione
We investigate the vacuum and thermal fluctuations of a neutral massless scalar field living in Minkowski spacetime and interacting with a finite number of point-like obstacles, mo…
Homogenization of point interactions
Domenico Cafiero, Michele Correggi, Davide Fermi
We consider a non-relativistic quantum particle in , or , interacting with singular zero-range potentials concentrated on a large collection of points. W…
On two-dimensional Dirac operators with critical delta-shell interactions
William Borrelli, Pietro Carimati, Davide Fermi
We study two-dimensional Dirac operators with singular interactions of electrostatic and Lorentzscalar type, supported either on a straight line or a circle. For certain critical v…
The Aharonov-Bohm Hamiltonian: self-adjointness, spectral and scattering properties
Davide Fermi
This work provides an introduction and overview on some basic mathematical aspects of the single-flux Aharonov-Bohm Schrödinger operator. The whole family of admissible self-adjoin…
Pauli Hamiltonians with an Aharonov-Bohm Flux
William Borrelli, Michele Correggi, Davide Fermi
We study a two-dimensional Pauli operator describing a charged quantum particle with spin moving on a plane in presence of an orthogonal Aharonov-Bohm magnetic flux. We class…
Deficiency indices for singular magnetic Schrödinger operators
Michele Correggi, Davide Fermi
We show that the deficiency indices of magnetic Schrödinger operators with several local singularities can be computed in terms of the deficiency indices of operators carrying just…
