Two-dimensional Rashba metals: unconventional low-temperature transport properties
Valentina Brosco, Claudio Grimaldi, Emmanuele Cappelluti +1
Rashba spin-orbit coupling emerges in materials lacking of structural inversion symmetry, such as heterostructures, quantum wells, surface alloys and polar materials, just to menti…
Unconventional dc transport in Rashba electron gases
Valentina Brosco, Lara Benfatto, Emmanuele Cappelluti +1
We discuss the transport properties of a disordered two-dimensional electron gas with strong Rashba spin-orbit coupling. We show that in the high-density regime where the Fermi ene…
Energy levels of a two-dimensional hydrogen atom with spin-orbit Rashba interaction
C. Grimaldi
Electronic bound states around charged impurities in two-dimensional systems with structural inversion asymmetry can be described in terms of a two-dimensional hydrogen atom in the…
Topological Change of the Fermi Surface in Low Density Rashba Gases: Application to Superconductivity
E. Cappelluti, C. Grimaldi, F. Marsiglio
Strong spin-orbit coupling can have a profound effect on the electronic structure in a metal or semiconductor, particularly for low electron concentrations. We show how, for small…
Spin-Hall Conductivity in Electron-Phonon Coupled Systems
C. Grimaldi, E. Cappelluti, F. Marsiglio
We derive the ac spin-Hall conductivity of two-dimensional spin-orbit coupled systems interacting with dispersionless phonons of frequency . For the linear Ras…
Off-Fermi surface cancellation effects in spin-Hall conductivity of a two-dimensional Rashba electron gas
C. Grimaldi, E. Cappelluti, F. Marsiglio
We calculate the spin-Hall conductivity of a disordered two-dimensional Rashba electron gas within the self-consistent Born approximation and for arbitrary values of the electron d…
