摘要：

The understanding of the underlying dynamical mechanisms which determines the macroscopic laws of heat conduction is a long standing task of non-equilibrium statistical mechanics. A better understanding of such mechanism may also lead to potentially interesting applications based on the possibility to control the heat flow. Indeed, a model of thermal rectifier has been proposed in which heat can flow preferentially in one direction. The proposed rectifying mechanism is of very general nature and theoretical and experimental work is currently undergoing.

In particular we discuss different dynamical models which exhibit rectification and interesting phenomena such as self-organization and 1d non equilibrium phase transition.

We then discuss a new approach, which is rooted in nonlinear dynamical systems, for increasing the efficiency of thermoelectric machines. The main focus will be on the physical mechanisms, unveiled by these dynamical models, which lead to high thermoelectric efficiency, approaching the Carnot limit. The role of conservation laws and symmetry breaking will be emphasized.

摘要：Given two quantum systems how can we decide which one is more complex than the other? In classical mechanics the notion of complexity is rooted in the local exponential instability which leads to dynamical chaos. Such property is absent in quantum mechanics. Here we discuss the deep implications that chaos and entanglement have in characterizing quantum many-body dynamical complexity.
