Current-phase relation and Josephson inductance in a superconducting Cooper-pair transistor
Current-phase relation and Josephson inductance in a superconducting Cooper-pair transistor
We have investigated the Josephson inductance ${L}_{J}$ of a superconducting Cooper pair transistor (SCPT). We traced the inductance using microwave reflection measurements on a tuned resonance circuit in which a SCPT was mounted in parallel to a $\ensuremath{\sim}200\text{ }\text{pH}$ strip line inductance. When the inverse of the Josephson inductance, determined …
