Heat rectification, heat fluxes, and spectral matching
Javier Navarro, Juan Gonzalo Muga, Marisa Pons
Heat rectifiers would facilitate energy management operations such as cooling, or energy harvesting, but devices of practical interest are still missing. Understanding heat rectifi…
Heat rectification with a minimal model of two harmonic oscillators
M. A. Simón, A. Alaña, M. Pons +2
We study heat rectification in a minimalistic model composed of two masses subjected to on-site and coupling linear forces in contact with effective Langevin baths induced by laser…
Local rectification of heat flux
M. Pons, Y. Y. Cui, A. Ruschhaupt +2
We present a chain-of-atoms model where heat is rectified, with different fluxes from the hot to the cold baths located at the chain boundaries when the temperature bias is reverse…
Exact non-equilibrium solutions of the Boltzmann equation under a time-dependent external force
D. Guéry-Odelin, J. G. Muga, M. J. Ruiz-Montero +1
We construct a novel class of exact solutions to the Boltzmann equation, in both its classical and quantum formulation, for arbitrary collision laws. When the system is subjected t…
