Lecture 6 Josephson Junctions

Superconductivity lectures by Kaveh Lahabi at Leiden University. Link to the lecture slides: https://www.lahabilab.com/teaching Lecture 6 covers: The Josephson equations (the current-phase relation and the voltage-phase relation in Josephson devices), Josephson potential, the tilted washboard potential model, critical current, re-trapping current, RCSJ model, overdamped vs underdamped junctions, SQUIDs, supercurrent interreference, Fraunhofer pattern, double-slit interference pattern, Shapiro steps, 0 and π junctions, 0-π SQUID, 0-π junctions, φ and φ_0 junctions, and superconducting phase batteries.
