Superfluid 3He: the early days as seen by a theorist

Tony Leggett, University of Illinois at Urbana-Champaign
Wigner Auditorium, 4500N

I present a very personal account of the way in which, in the approximately 12 months between July 1972 and July 1973, we came to a theoretical understanding of the puzzling experimental data on what we now know as superfluid 3He. I particularly emphasize the concept of "spontaneously broken spin-orbit symmetry" which turned out to be a key ingredient in understanding the NMR behavior.

NOTE: Tony Leggett was awarded the 2003 Nobel Laureate in Physics.
