“…An analogous case, but at the quantum mechanical level, is the one of carriers embedded in the ionic lattice in doped or photoinjected semiconductors (see for example Refs. [41][42][43][44][45][46][47][48]). …”

Construction, in the framework of a nonequilibrium statistical ensemble formalism, of a higher-order generalized hydrodynamics, also referred to as mesoscopic hydrothermodynamics, that is, covering phenomena involving motion of fluids displaying variations short in space and fast in time-unrestricted values of Knudsen numbers, is presented. In that way, an approach is provided enabling the coupling and simultaneous treatment of the kinetics and hydrodynamic levels of descriptions. It is based on a complete thermostatistical approach in terms of the densities of matter and energy and their fluxes of all orders covering systems arbitrarily driven away from equilibrium. The set of coupled nonlinear integrodifferential hydrodynamic equations is derived. They are the evolution equations of the Gradlike moments of all orders, derived from a generalized kinetic equation built in the framework of the nonequilibrium statistical ensemble formalism. For illustration, the case of a system of particles embedded in a fluid acting as a thermal bath is fully described. The resulting enormous set of coupled evolution equations is of unmanageable proportions, thus requiring in practice to introduce an appropriate description using the smallest possible number of variables. We have obtained a hierarchy of Maxwell times, associated to the set of all the higher-order fluxes, which have a particular relevance in the process of providing criteria for establishing the contraction of description.

“…Poderosas teorias estocásticas estão também disponíveis dentro do enfoque sinergético de Haken [42]. Como descrito há algum tempo [19], nosso Grupo no IFGW-Unicamp tem proposto que em certas situações um tratamento ao nível microscópico (molecular e atômico) para evidenciar e descrever estruturas dissipativas auto-organizadas pode ser constituído pela mecânica estatística de não-equilíbrio, que aplicamos ao caso de sistemas semicondutores dopados [59][60][61][62] e fotoexcitados [63][64][65] e sistemas biológicos modelados [30].…”

<p>Neste artigo consideramos os aspectos gerais dos temas emergentes na segunda metade do século passado, de complexidade, auto-organização e informação. Os três estão ligados pelo fato de estarem envolvidos na “teoria de sistemas dinâmicos”, e sobre esse ponto enfocamos a descrição aqui apresentada. Descreve-se o surgimento de comportamento complexo em tais sistemas dinâmicos em geral quando governados por uma teoria cinética não linear, a emergência de estruturas dissipativas sinergéticas à la Prigogine-Haken, e a teoria de informação via o enfoque de inferência científica proposto por Jeffreys-Jaynes.</p>

“…Seeking a better understanding of the carrier transport in ZnS(WZ) and in ZnS(ZB), a theoretical study of the electron drift velocity was performed in this work. For this, we used a kinetic theory for far-from equilibrium systems: the "Non-Equilibrium Statistical Operator Method" [15], which provides an elegant, practical, and physically clear picture of irreversible processes [16,17]; for example, in far-from equilibrium semiconductors [18][19][20][21][22], which is the case considered here. This method was used in numerous works for studying transport processes and kinetic phenomena (e.g., [23][24][25]).…”

Abstract:In this paper, we analyzed the ultrafast transient transport in n-doped ZnS in wurtzite and zincblende phases, driven far away from equilibrium by an electric field. Through the numerical solution of associate quantum transport equations based on the Non-Equilibrium Statistical Operator Method, the time evolution of the electron drift velocity and the non-equilibrium temperature of electrons and phonons were obtained, analyzing the dependence on the electric field strength.
