Last week I gave half a
lecture on the
phase diagram of helium and superfluidity to a second year undergraduate class on
Thermodynamics and Condensed Matter Physics. The lecture includes:
- a discussion of the differences between the phase diagrams of 3He and 4He
- a list of the 4 Nobel Prizes awarded for work in superfluidity [Landau, Kapitsa, Osheroff, Richardson, and Lee, Leggett] (I did not include BECs but should have]
- a video of the superfluid transition
- a discussion of an amazing experiment on the space shuttle which determined the critical exponent for the specific heat at the superfluid (lambda) transition to five significant figures.
