| Abstract: | Understanding transport phenomena in the micro scale is of interest from both the fundamental theoretical point of view as well as the practical one. The problem of classical heat conduction in 1D system is a well known one. The problem regards the validity of Fourier law in this setting. In our research we investigate the heat transfer in broader context, taking into account the non-stationary processes. In this talk we will report the investigation of the phenomena of non- stationary heat conduction in one-dimensional linear and nonlinear chains (classical models of dielectrics), by combining molecular dynamics simu- lations and analytic investigation. Two main aspects of our research were the transport of kinetic energy through periodic chains (both integrable and non-integrable) and through disordered chains. We also investigate how the effects of disorder affect the transport mechanism |
