Heat-charge separation in a hybrid superconducting quantum Hall setup

Abstract

Separating heat from charge in a material is an extremely challenging task since they are transported by the very same carriers, i.e. electrons or holes. In this Letter we show that such separation can reach 100% efficiency in a hybrid superconducting quantum Hall setup, provided that the quantum Hall system is tuned to integer filling factor. We present microscopic calculations for a three-terminal setup to illustrate our idea.
