Summary

A new method for cooling below 1 K, the superfluid Stirling cycle, uses the gaslike thermodynamic properties of the helium 3 solute in a superfluid helium 3-helium 4 solution. The first prototype superfluid Stirling-cycle refrigerator cools to 0.6 K from a starting temperature of 1.2 K, with cooling powers at the lowest temperatures of a few tens of microwatts. The cycle works in both classical-gas and Fermi-gas regimes.
