Josephson effect in Superconductors and Superfluids
arXiv:0908.1761
Abstract
We present a brief pedagogical introduction into the basic physics of the Josephson effect in superconductors and Bose-Einstein condensates. We show how the critical Josephson current between two superconductors can be derived microscopically. We also shortly discuss the Josephson effect in superfluid Helium.
