  • Increasing thermal rectification: effects of long-range interactions.
    Physical review. E Statistical nonlinear and soft matter physics, 2013
    Co-Authors: Emmanuel Pereira, Ricardo R. Ávila
    Abstract:

    In this paper, we study the effects of the interparticle interaction range on heat flow. We show that, by increasing the interaction range, we may amplify the thermal conductivity and even change the regime of heat transport. More importantly, considering a crucial problem of phononics, namely, the search of a suitable thermal diode, we investigate the range effects in some graded systems in which thermal rectification is a ubiquitous phenomenon. In such graded models, we show that long-range interactions may significatively increase the rectification power and may avoid its decay with the system size, thus solving relevant problems of the usual proposals of rectifiers. Our results indicate that graded materials are genuine candidates for the Actual Fabrication of thermal diodes.

  • Thermal rectification in graded materials.
    Physical review. E Statistical nonlinear and soft matter physics, 2012
    Co-Authors: Jiao Wang, Emmanuel Pereira, Giulio Casati
    Abstract:

    In order to identify the basic conditions for thermal rectification we investigate a simple model with nonuniform, graded mass distribution. The existence of thermal rectification is theoretically predicted and numerically confirmed, suggesting that thermal rectification is a typical occurrence in graded systems, which are likely to be natural candidates for the Actual Fabrication of thermal diodes. In view of practical implications, the dependence of rectification on the asymmetry and system's size is studied.
