Query: Rashba spin splitting in quantum wires   This article presents an overview of results pertaining to electronic
structure, transport properties, and interaction effects in ballistic quantum
wires with Rashba spin splitting. Limits of weak and strong spin--orbit
coupling are distinguished, and spin properties of the electronic states
elucidated. The case of strong Rashba spin splitting where the spin--precession
length is comparable to the wire width turns out to be particularly
interesting. Hybridization of spin--split quantum--wire subbands leads to an
unusual spin structure where the direction of motion for electrons can fix
their spin state. This peculiar property has important ramifications for linear
transport in the quantum wire, giving rise to spin accumulation without
magnetic fields or ferromagnetic contacts. A description for interacting
Rashba--split quantum wires is developed, which is based on a generalization of
the Tomonaga--Luttinger model.
