Weak measurement og the composite Goo-Haenchen shift in the critical region
Octavio J. S. Santana, Silvania A. Carvalho, Stefano De Leo +1
By using a weak measurement technique, we investigated the interplay between the angular and lateral Goos-Haenchen shift of a focused He-Ne laser beam for incidence near the criti…
A study of transit times in Dirac tunneling
Stefano De Leo
Based on the Dirac equation, the behavior of relativistic electrons which tunnel a potential barrier of height V0 for incoming energies between V0 and V0+m is studied by using the…
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…
Relativistic tunneling through opaque barriers
Stefano De Leo, Vinicius Leonardi
We propose an analytical study of relativistic tunneling through opaque barriers. We obtain a closed formula for the phase time. This formula is in excellent agreement with the num…
A New Phase Time Formula for Opaque Barrier Tunneling
Stefano De Leo, Vinicius Leonardi
After a brief review of the derivation of the standard phase time formula, based on the use of the stationary phase method, we propose, in the opaque limit, an alternative method t…
Planar Dirac diffusion
Stefano De Leo, Pietro Rotelli
We present the results of the planar diffusion of a Dirac particle by step and barrier potentials, when the incoming wave impinges at an arbitrary angle with the potential. Except…
Octonionic Dirac Equation
Stefano De Leo, Khaled Abdel-Khalek
In order to obtain a consistent formulation of octonionic quantum mechanics (OQM), we introduce left-right barred operators. Such operators enable us to find the translation rules…
Octonionic Quantum Mechanics and Complex Geometry
Stefano De Leo, Khaled Abdel-Khalek
The use of complex geometry allows us to obtain a consistent formulation of octonionic quantum mechanics (OQM). In our octonionic formulation we solve the hermiticity problem and d…
Half-whole Dimensions in Quaternionic Quantum Mechanics
Stefano De Leo
We introduce {\em half-whole} dimensions for quaternionic matrices and propose a quaternionic version of the Frobenius-Schur theorem which allows us to obtain the proper quaternion…
Odd Dimensional Translation between Complex and Quaternionic Mechanics
Stefano De Leo, Pietro Rotelli
We complete the rules of translation between standard complex quantum mechanics (CQM) and quaternionic quantum mechanics (QQM) with a complex geometry. In particular we describe ho…
Quaternionic Electroweak Theory
Stefano De Leo, Pietro Rotelli
We explicitly develop a quaternionic version of the electroweak theory, based on the local gauge group . The need of a complex projection for our Lagra…
