Polaron formation as a genuine nonequilibrium phenomenon
arXiv:0907.0218 · doi:10.1103/PhysRevB.83.212301
Abstract
Solitons and polarons at nonequilibrium steady states are investigated for the spinless Takayama Lin-Liu Maki model. Polarons are found to be possible {\it only out of equilibrium}. This polaron formation is a genuine nonequilibrium phenomenon, as there is a lower threshold current below which they cannot exist. It is considered to be an example of microscopic dissipative structure.
