Current in coherent quantum systems connected to mesoscopic Fermi reservoirs
S. Ajisaka, F. Barra, C. Mejia-Monasterio +1
We study particle current in a recently proposed model for coherent quantum transport. In this model a system connected to mesoscopic Fermi reservoirs (meso-reservoir) is driven ou…
Polaron formation as a genuine nonequilibrium phenomenon
S. Ajisaka, S. Tasaki, I. Terasaki
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}…
Static Soliton at Nonequilibrium Steady State
S. Ajisaka, S. Tasaki, I. Terasaki
Nonequlibrium phase transition of an open Takayama-Lin Liu-Maki chain coupled with two reservoirs is investigated. We will show that solitons connecting two uniform phases are poss…
Nonequilibrium Peierls Transition
Shigeru Ajisaka, Hisashi Nishimura, Shuichi Tasaki +1
Nonequlibrium phase transition of an open Takayama-Lin Liu-Maki chain coupled with two reservoirs is investigated by combining a mean-field approximation and a formula characterizi…
