The one-dimensional Coulomb Hamiltonian: Properties of its Birman-Schwinger operator

S. Fassari, M. Gadella, J. T. Lunardi +2

We study the Birman-Schwinger operator for a self-adjoint realisation of the one-dimensional Hamiltonian with the Coulomb potential. We study both the case in which this Hamiltonia…

The Schrödinger particle on the half-line with an attractive $δ$ -interaction: bound states and resonances

S. Fassari, M. Gadella, L. M. Nieto +1

In this paper we provide a detailed description of the eigenvalue $E_{D} (x_{0}) \leq 0$ (respectively $E_{N} (x_{0}) \leq 0$ ) of the self-adjoint Hamiltonian operator representing the n…

The Birman-Schwinger Operator for a Parabolic Quantum Well in a Zero-Thickness Layer in the Presence of a Two-Dimensional Attractive Gaussian Impurity

Sergio Albeverio, Silvestro Fassari, Manuel Gadella +2

In this note we consider a quantum mechanical particle moving inside an infinitesimally thin layer constrained by a parabolic well in the $x$ -direction and, moreover, in the presen…
