Thermal Transport in Low Dimensions : From Statistical Physics to Nanoscale Heat Transfer Heat transport in low dimensions: introduction and phenomenology Heat transport in harmonic systems Fluctuating hydrodynamics approach to equilibrium time correlations for anharmonic chains Kinetic theory of phonons in weakly anharmonic particle chains Thermal conductivity in harmonic lattices with random collisions Simulation of heat transport in low dimensional oscillator lattices Simulation of dimensionality effects in thermal transport Experimental Probing of Non‐Fourier Thermal Conductors Thermal Transport in Graphene Few Layer Graphene and Graphene Nanoribbons From thermal rectifiers to thermoelectric devices. Understanding non equilibrium properties of classical and quantum many particle systems is one of the goals of contemporary statistical mechanics. Besides its own interest for the theoretical foundations of irreversible thermodynamics(e.g. of the Fouriers law of heat conduction) this topic is also relevant to develop innovative ideas for nanoscale thermal management with possible future applications to nanotechnologies and effective energetic resources. The first part of the volume (Chapters 1 6) describes the basic models the phenomenology and the various theoretical approaches to understand heat transport in low dimensional lattices (1D e 2D). The methods described will include equilibrium and nonequilibrium molecular dynamics simulations hydrodynamic and kinetic approaches and the solution of stochastic models. The second part (Chapters 7 10) deals with applications to nano and microscale heat transfer as for instance phononic transport in carbon based nanomaterials including the prominent case of nanotubes and graphene. Possible future developments on heat flow control and thermoelectric energy conversion will be outlined. This volume aims at being the first step for graduate students and researchers entering the field as well as a reference for the community of scientists that from different backgrounds (theoretical physics mathematics material sciences and engineering) has grown in the recent years around those themes.
