Isospectrality and non-locality of generalized Dirac combs
Giuliano Angelone, Manuel Asorey, Fernando Ezquerro +1
We consider a generalization of Dirac's comb model, describing a non-relativistic particle moving in a periodic array of generalized point interactions. The latter represent the mo…

Classical echoes of quantum boundary conditions
Giuliano Angelone, Paolo Facchi, Marilena Ligabò
We consider a non-relativistic particle in a one-dimensional box with all possible quantum boundary conditions that make the kinetic-energy operator selfadjoint. We determine the W…
