Meccanica statistica di non equilibrio: trasporto e diffusione in sistemi complessi

Relatore: Stefano Lepri

Gli argomenti di tesi sono di tipo teorico e riguardano il comportamento di sistemi fuori equilibrio. Una preparazione di base in meccanica statistica e’ essenziale. La conoscenza di un linguaggio di programmazione per lo sviluppo di codici di simulazione e’ auspicabile.

Diffusione anomala

Il moto di una particella soggetta a forze aleatorie e’ descritto dalle leggi del moto browniano (diffusione).… Read the rest

Anomalous Heat Transport in Low Dimensions

in

Many phenomena in nature occur under nonequilibrium stationary conditions. For instance, an electric current is obtained by applying an electric field along a conductor or heat is transported when a temperature gradient is established between two boundaries of a material. Despite their ubiquiteness and importance in everyday life many aspects of such phenomena are still under debate in the theoretical physics community.

Asymmetric Wave Transport in Nonlinear System

in

Deterministic chaos, fractal structures and other beautiful phenomena are manifestations of the nonlinear character of forces which govern our world. Besides a revolutionary change in our approach to predictability, these discoveries had great impact on technological applications.  Among the most fascinating ones is  the possibility to control energy flows by tuning nonlinear features of complex materials.

In the context of wave propagation trough nonlinear media, the simplest form of control would be to devise a “wave diode”  in which electromagnetic or elastic waves are transmitted differently along two opposite propagation directions.… Read the rest
