Adiabatic Pumping in a Superconductor-Normal-Superconductor Weak Link
Adiabatic Pumping in a Superconductor-Normal-Superconductor Weak Link
We present a formalism to study adiabatic pumping through a superconductor-normal-superconductor weak link. At zero temperature, the pumped charge is related to the Berry phase accumulated, in a pumping cycle, by the Andreev bound states. We analyze in detail the case when the normal region is short compared to the …
