Researchers at Quantronics group at SPEC (Joint Reserach Unit UMR CEA-CNRS), in collaboration with Laboratoire de Physique de l’École Normale Supérieure – LPENS (UMR ENS, CNRS, Sorbonne Université, Université Paris Cité), have theoretically investigated heat and charge transport through a chain of small metallic islands connected by ballistic channels. Their calculations reveal that electron interactions…
