| Résumé : | Transport properties play a central role in irreversible processes dissipating energy and producing entropy at the macroscopic scale. Hydrodynamic equations describe the different phases of matter and are formulated in terms of transport properties through the so-called transport coefficients. For example, they include thermal conductivity, diffusion, viscosity, or thermodiffusion. A fundamental issue is to understand the origin of these transport properties in terms of the underlying quantum dynamics of particles moving in matter, as well as the microscopic basis of the hydrodynamic equations. To this end, the local equilibrium approach is formulated in the context of quantum mechanics. The entropy production and the dissipativeless and dissipative parts of the current densities are deduced, allowing to reconstruct the hydrodynamic equations as well as the quantum Green-Kubo formulas for the transport coefficients. The consequences of the spatial symmetries and the microreversibility of the system on the transport properties are investigated. |
