Description
We study the interplay of electron-electron interactions and Rashba
spin-orbit coupling in one-dimensional ballistic wires. Using the
renormalization group approach we construct the phase diagram
in terms of Rashba coupling, Tomonaga-Luttinger stiffness
and backward scattering strength. We identify the parameter regimes
with a dynamically generated spin gap and show where the Luttinger
liquid prevails.
We also discuss the consequences for the operation of the spintronical
devices lika the Datta-Das transistor.
