Temperature and voltage probes far from equilibrium
We consider an open system of non-interacting electrons consisting of a small sample connected to several reservoirs and temperature or voltage probes. We study the non-linear system of equations that determines the probe parameters. We show that it has a unique solution, which can be computed with a fast converging iterative algorithm. We illustrate our method with two well-known models: the t...
متن کاملMean-field "temperature" in far from equilibrium systems.
We calculate the nonequilibrium mean-field "temperature" of a brownian system in contact with a heat bath. We consider two different cases: an equilibrium bath in the presence of strong external forces, and a nonequilibrium bath. By proving the existence of a generalized fluctuation-dissipation relation, this mean-field "temperature" can be used to describe a nonequilibrium system as is if it w...
متن کاملFar-from-equilibrium computation
We study the possibility of developing far-from-equilibrium computational systems, in analogy with corresponding self-organizing physical systems. We review the computational models developed in analogy with physical systems converging towards equilibrium and the research related to the self-organization of far-from-equilibrium physical systems. Based on this review, we define several nonequili...
متن کاملIsotropization far from equilibrium
Isotropization occurs on time scales much shorter than the thermal equilibration time. This is a crucial ingredient for the understanding of collision experiments of heavy nuclei or other nonequilibrium phenomena in complex many body systems. We discuss in detail the limitations of estimates based on standard “linear” or relaxationtime approximations, where isotropization and thermal equilibrat...
متن کاملUltracold gases far from equilibrium
Ultracold atomic quantum gases belong to the most exciting challenges of modern physics. Their theoretical description has drawn much from (semi-) classical field equations. These mean-field approximations are in general reliable for dilute gases in which the atoms collide only rarely with each other, and for situations where the gas is not too far from thermal equilibrium. With present-day tec...
