Antiparticle creation in tunneling
Stefano De Leo, Pietro Rotelli
We study particle interaction with a Dirac step potential. In the standard Klein energy zone, the hypothesis of Klein pair production predicts the existence of free/oscillatory ant…
Relative helicity phases in planar Dirac scattering
Stefano De Leo, Pietro Rotelli
We study planar Dirac scattering for an electrostatic stratified barrier potential. The general expressions for transmitted and reflected waves are derived. Of particular interest…
Graphene tests of Klein phenomena
Stefano De Leo, Pietro Rotelli
Graphene is characterized by chiral electronic excitations. As such it provides a perfect testing ground for the production of Klein pairs (electron/holes). If confirmed, the stand…
Wave and Particle Limit for Multiple Barrier Tunneling
Stefano De Leo, Pietro Rotelli
The particle approach to one-dimensional potential scattering is applied to non relativistic tunnelling between two, three and four identical barriers. We demonstrate as expected t…
Localized Beams and Dielectric Barriers
Stefano De Leo, Pietro Rotelli
Recalling the similarities between the Maxwell equations for a transverse electric wave in a stratified medium and the quantum mechanical Schroedinger equation in a piece-wise pote…
Fermion-Fermion Bound State Condition for Scalar Exchanges
Stefano De Leo, Pietro Rotelli
The condition for the existence of a bound state between two fermions exchanging massive scalars is derived. For low scalar mass, we reproduce the scalar field model result. The hi…
