Quantum-like behavior of 1D nonequilibrium system in the maximum heat flux limit

Abstract: Using information entropy formalism, we consider a one-dimensional system with heat flux and extend the meaning of equilibrium variables to non equilibrium scenarios when classical local equilibrium approach is not applicable; this is particularly important for the performance evaluation of modern thermal systems and microdevices, which usually operate in extreme situations. The extended non equilibrium entropy, temperature, thermal conductivity and heat capacity have been analyzed as functions of the local energy density (kinetic temperature) and heat flux.
