Magnetic field tuning and quantum interference in a Cooper pair splitter

G Fülöp, F Domínguez, S d'Hollosy, A Baumgartner… - Physical review …, 2015 - APS
Cooper pair splitting (CPS) is a process in which the electrons of the naturally occurring spin-
singlet pairs in a superconductor are spatially separated using two quantum dots. Here, we …

Interference-induced thermoelectric switching and heat rectification in quantum Hall junctions
