Multifractal Wave Functions of a System with a Monofractal Energy Spectrum
Masayuki Tashima, Shuichi Tasaki
We show the appearance of multifractal wave functions on a one-dimensional quasiperiodic system that has a monofractal energy spectrum. Using the Mantica technique, we construct th…
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…
Fluctuation theorem for currents in open quantum systems
David Andrieux, Pierre Gaspard, Takaaki Monnai +1
A quantum-mechanical framework is set up to describe the full counting statistics of particles flowing between reservoirs in an open system under time-dependent driving. A symmetry…
Calculation of Correlation Functions in Terms of Fluctuation Relation
Takaaki Monnai, Shuichi Tasaki
We derive a relation similar to the fluctuation theorem for work done on a system obeying Langevin dynamics with thermal and colored noises. Then, we propose a method of calculatin…
