We analyze the role played by nonlocal and nonlinear effects in the propagation of thermal and elastic high-frequency waves in nanosystems. The study is performed both in the case of a rigid body (i.e., for heat-pulse propagation) and in the case of a nonrigid body (i.e., for thermoelastic-pulse propagation). In the framework of extended irreversible thermodynamics, the compatibility of our theoretical models with second law is proved.

Abstract
We analyze the role played by nonlocal and nonlinear effects in the propagation of thermal and elastic high-frequency waves in nanosystems. The study is performed both in the case of a rigid body (i.e., for heat-pulse propagation) and in the case of a nonrigid body (i.e., for thermoelastic-pulse propagation). In the framework of extended irreversible thermodynamics, the compatibility of our theoretical models with second law is proved.File in questo prodotto:
