We consider the Gibbs representation over space-time of non-equilibrium dynamics of Hamiltonian systems defined on a lattice with local interactions. We first write the corresponding action functional as a sum of local terms, defining a local action functional. We replace the local system by a translationinvariant system whose dynamics has an identical space-time characterization. We study in d...

The domination by Local Thermal Non-Equilibrium (LTNE) with regard to the onset of Darcy-Rayleigh-Benard-Marangoni (DRBM) convection swayed magnetic field in a composite layer set-up is studied pertinent incompressible fluid. precinct above fluid presumed be free and that below porous rigid. Regular perturbation technique exercised on acquired problem achieve analytical solution taking adiabati...

in a temperature gradient, see Fig.1. This is of our knowledge the first molecular dynamics study of a reacting system submitted to non-equilibrium conditions. The reaction, which is diffusion controlled, was investigated at and close to local chemical equilibrium. The transport properties are determines; i.e. diffusion, thermal conductivity and the coupling between transport of heat and mass. ...

Within the Closed Time Path Formalism of Thermal Field Theory we calculate the hard photon emission rate as well as the collisional energy-loss rate for a quark-gluon plasma away from chemical equilibrium. Mass singularities are shown to be dynamically screened within HTL-resummed perturbation theory also away from equilibrium. Additional (pinch) singularities are absent and well defined result...

A crucial assumption in the conventional description of thermal conduction is the existence of local thermal equilibrium. We test this assumption in two simple models of heat conduction. Our first model is a linear chain of planar spins with nearest neighbour couplings, and the second model is that of a Lorentz gas. We look at the steady state of the system when the two ends are connected to he...

This work addresses electro-thermal simulation of LDMOS devices and associated non-equilibrium effects. Simulations have been performed on three kinds of LDMOS i.e. bulk Si, partial SOI and SOI, with a view to compare the extent of non-equilibrium in each. Phonon temperature contours and electron energies were analyzed in each case. The results indicate that, under similar operating conditions,...
