Sentences with word «nonequilibrium»

Discussion of whether a criterion of relative stability of nonequilibrium steady states exists is currently being carried out in the literature.

As the concentration of reagent is increased, the system would be taken beyond the chemical instability, and there would be two equally probable nonequilibrium steady states.

Our work compares the predictions of a theory of nonequilibrium phase transitions with nonstandard statistical signatures of earthquake complex scaling behaviors.

In the field of nonequilibrium dynamics, there are interesting phenomena, such as the Belousov Zhabotinsky systems, which exhibit complex ordered features (going under the general field of self - organising systems).

Abstract: We investigate nonequilibrium behavior in (1 +1)- dimensional stochastic field theories in the context of Ginzburg - Landau models at varying cooling rates.

A chemical dissipative structure comes into existence when environmental conditions of a complex open system change, so that an equilibrium state becomes unstable, and a network of relationships (among components of the system) gives rise to several nonequilibrium steady states.

However, if fluctuations (that exceed certain minimum values in magnitude and extent) are included, then the instability of the initial (Nigerian) steady state is demonstrated, and the system approaches one (Irish) or the other (Ivory Coastian) of the two stable nonequilibrium steady states.

An interesting question is: how does the system decide which of the two possible nonequilibrium steady states to approach?

Both lowering of the activation free energy and changes in the generalized transmission coefficient (recrossing of the transition state, tunneling, and nonequilibrium contributions) can play a role.

This heat - conduction localization phenomenon is confirmed by nonequilibrium atomic Green's function simulation.

Ab Initio Calculations of Nonequilibrium Coupled Carrier and Phonon Dynamics.

This work is based on a weaving together of recent results from three mathematical disciplines: the ergodic theory of dynamical systems, stochastic processes, and the response theory of nonequilibrium dynamical systems.

Nonequilibrium phase transitions, which are defined by the formation of macroscopic transient domains, are optically dark and can not be observed through conventional temperature - or pressure - change studies.

In a new dissipative structure (either a steady state or a limit cycle), concentrations of chemicals and rates of mass - transfer between the system and surroundings will not be those characteristic of the previous equilibrium state (or the nonequilibrium steady state that corresponds to it under conditions of instability) but rather they will be the (perhaps quite different) average values which pertain to the new structure.
