Unconventional dc Transport in Rashba Electron Gases.
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 energy overcomes the energy associated with spin-orbit coupling, dc transport is accurately described by a standard Drude's law, due to a nontrivial compensation between the suppression of backscattering and the relativi...
متن کاملSupplemental Material to “ Unconventional dc Transport in Rashba Electron Gases ”
To fix the notation, let us start by giving some details on the helicity eigenstates basis. The helicity operator is defined as S = [p̂⇥ ~ ]z and its eigenstates, |ksi, with s = ±1, satisfy the relation S|k±i = ±|k±i. A simple calculation shows in particular that |k±i can be expressed in terms of the standard spin eigenstates, |k "i and |k #i, as |k±i = (exp ( i✓k)|k "i± i|k #i)/ p 2 with ✓k = a...

We investigate transport in a granular metallic system at large tunneling conductance between the grains, g(T)>>1. We show that at low temperatures, Tg(T)delta) behavior where conductivity is controlled by the sc...
