Geometric origin of Elliott spin decoherence in metals and semiconductors.
It has been shown that the Elliott spin-decoherence mechanism in nonmagnetic metals and semiconductors arises from the random acquisition of geometric phases and represents a special case of a more general situation-relaxation of the pseudo-spin-1/2 induced by stochastic gauge fields. The geometric approach gave an opportunity to apply Elliott's ideas for a wide range of systems and system parameters.
