Nonequilibrium effective vector potential due to pseudospin exchange in graphene
arXiv:0711.4150 · doi:10.1103/PhysRevLett.101.226809
Abstract
We show that exchange interactions in two-dimensional electron gases out of equilibrium can generate a fictitious vector potential with intriguing signatures in interference and Hall measurements. Detailed predictions are made for graphene, where the effect is enhanced by pseudospin exchange.
