Bound States and Resonance Analysis of One-Dimensional Relativistic Parity-Symmetric Two Point Interactions
Carlos A. Bonin, Manuel Gadella, José T. Lunardi +1
We consider the one-dimensional Dirac equation with the most general relativistic contact interaction supported on two points symmetrically located with respect to the origin. In o…
Planar Dirac equation with radial contact potentials
J. T. Lunardi, S. Salamanca, J. Negro +1
We investigate the planar Dirac equation with the most general time-independent contact (singular) potential supported on a circumference. Taking advantage of the radial symmetry,…
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…
A probability distribution for quantum tunneling times
José T. Lunardi, Luiz A. Manzoni
We propose a general expression for the probability distribution of real-valued tunneling times of a localized particle, as measured by the Salecker-Wigner-Peres quantum clock. Thi…
A note on Duffin-Kemmer-Petiau equation in (1+1) space-time dimensions
José T. Lunardi
In the last years several papers addressed the supposed spin-1 sector of the massive Duffin-Kemmer-Petiau (DKP) equation restricted to (1+1) space-time dimensions. In this note we…
Distributional approach to point interactions in one-dimensional quantum mechanics
Marcos Calçada, José T. Lunardi, Luiz A. Manzoni +1
We consider the one-dimensional quantum mechanical problem of defining interactions concentrated at a single point in the framework of the theory of distributions. The often ill-de…
