Ciclo incontri. Stefano Iubini Dipartimento di Fisica, Università di Firenze Coupled transport regimes occur when a system displays two or more species of irreversible flows that influence one another. Well known examples date back to the discoveries by Seebeck and Peltier of thermoelectricity in the first half of the XIX century and refer to the capacity of converting a temperature difference into a voltage (and vice-versa). From the point of view of statistical mechanics, the connection between microscopic interactions and macroscopic thermodynamic properties is still largely unexplored. In this talk, I will discuss how coupled transport effects arise in simple models of nonlinear interacting oscillators. Despite the simplicity of the microscopic particle-particle interaction, steady nonequilibrium states may be characterized by unusual complex features.
