Heat-charge separation in hybrid superconducting systems

Broadcast soon

MdM Quantum Meeting

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 a multiterminal device the heat and charge currents can however follow different paths. In this talk I will introduce and analyze a class of multiterminal devices where this property is pushed to its extreme limits, with charge and heat currents flowing in different reservoirs. In particular, I will 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.
