Proposes a holographic SNS junction in Einstein-Maxwell-charged-scalar AdS4 theory where the near-extremal RN-AdS throat supplies an infrared scaling mechanism for the Josephson critical current and phase stiffness after ordinary spatial suppression is removed.

abstract
We construct a gravitational dual of a Josephson junction. Calculations on the gravity side reproduce the standard relation between the current across the junction and the phase difference of the condensate. We also study the dependence of the maximum current on the temperature and size of the junction and reproduce familiar results.

Near extremal RN-AdS control of holographic Josephson transport
Proposes a holographic SNS junction in Einstein-Maxwell-charged-scalar AdS4 theory where the near-extremal RN-AdS throat supplies an infrared scaling mechanism for the Josephson critical current and phase stiffness after ordinary spatial suppression is removed.
