We discuss a quantum thermal machine that generates power from a thermally driven
double quantum dot coupled to normal and superconducting reservoirs. Energy exchange …

Optimal engine performances can be accomplished by quantum effects. Here we explore
two routes toward ideal engines, namely (1) quantum systems that operate as hybrid …

Coulomb drag experiments have been an essential tool to study strongly interacting low-
dimensional systems. Historically, this effect has been explained in terms of momentum …

Coulomb drag refers to the phenomenon in which a charge current in one electronic circuit
induces a responsive current in a neighbouring circuit solely through Coulomb interactions …

We study the thermal drag between two mesoscopic quantum Hall (QH) circuits. Each circuit
consists of an ohmic contact perfectly coupled to quantum Hall edge states. The drag is …

We develop a theory of fluctuation-driven phenomena in thermal transport in graphene
double-layers. We work in the regime of electron hydrodynamics and focus on the double …

We propose a new drag phenomenon, an interband magnon drag, and report on interaction
effects and multiband effects in magnon transport of ferrimagnetic insulators. We study a …

The phenomenon of universality is one of the most striking in many-body physics. Despite
having sometimes wildly different microscopic constituents, systems can nonetheless …
