Comment on “Dynamically induced heat rectification in quantum systems”
Résumé
The article by Riera-Campeny, Mehboudi, Pons, and Sanpera [Phys. Rev. E 99, 032126 (2019)] studies heat
rectification in a network of harmonic oscillators which is periodically driven. Both the title and introduction
stress the quantum nature of the system. Here we show that the results are more general and are equally valid
for a classical system, which broadens the interest of the paper and may suggest further pathways for a basic
understanding of the phenomenon.
