Relative helicity phases in planar Dirac scattering [PDF]
Stefano De Leo, Pietro RotelliWe study planar Dirac scattering for an electrostatic stratified barrier potential. The general expressions for transmitted and reflected waves are derived. Of particular interest is the information upon relative helicity phases. We also briefly discuss some possible applications.View original: http://arxiv.org/abs/1209.3698
