The Josephson Effect in Superfluids – Keith Schwab

Date: Tue. May 9th, 2000, 12:30 pm-1:30 pm
Location: Rockefeller 221

Since the development of the Superconducting Quantum Interference Device in the late 1960’s it has been appreciated that similar effects should exist in superfluids. In the past 10 years substantial progress has been made in observing these effects in both superfluid 3He and 4He. In this lecture, I will introduce the basic physics of the Josephson effect in superfluids and describe how these very delicate experiments are carried out. These new superfluid devices may have some very interesting applications as ultra-sensitive gyroscopes and possibly as quantum standards. –
