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…
Inclusion of radiation in the CCM approach of the model
S. Navarro-Obregón, L. M. Nieto, J. M. Queiruga
We present an effective Lagrangian for the model that includes radiation modes as collective coordinates. The coupling between these modes to the discrete part of the spectru…
An approximation to the Woods-Saxon potential based on a contact interaction
C. Romaniega, M. Gadella, R. M. Id Betan +1
We study a non-relativistic particle subject to a three-dimensional spherical potential consisting of a finite well and a radial - contact interaction at the well edge. This…
Solvable Quantum Two-Body Problem:Entanglement
ML Glasser, LM Nieto
A simple one dimensional model is introduced describing a two particle "atom" approaching a point at which the interaction between the particles is lost. The wave function is obtai…
