An efficient thermal diode with ballistic spacer
Shunda Chen, Davide Donadio, Giuliano Benenti +1
Thermal rectification is of importance not only for fundamental physics, but also for potential applications in thermal manipulations and thermal management. However, thermal recti…
Thermodynamic bound on heat to power conversion
Rongxiang Luo, Giuliano Benenti, Giulio Casati +1
In systems described by the scattering theory, there is an upper bound, lower than Carnot, on the efficiency of steady-state heat to work conversion at a given output power. We sho…
Perfect diode in quantum spin chains
Vinitha Balachandran, Giuliano Benenti, Emmanuel Pereira +2
We study the rectification of spin current in chains segmented in two parts, each with a different anisotropy parameter. Using exact diagonalization and a matrix product stat…
