Holographic Josephson Junction in 3+1 dimensions

Understand

In arXiv:1101.3326[hep-th], a (2+1)-dimensional holographic Josephson junction was constructed, and it was shown that the DC Josephson current is proportional to the sine of the phase difference across the junction.

• In this paper, we extend this study to a holographic description for the (3+1)-dimensional holographic DC Josephson junction.
• By solving numerically the coupled differential equations, we also obtain the familiar characteristics of Josephson junctions.
