Profile

At temperatures close to absolute zero helium-3, the light isotope of helium, forms a unique superfluid liquid where friction vanishes and all atoms are in the same quantum-mechanical state. This is the purest and most complex system for which we already have the “Theory of Everything”, and has an internal structure that mirrors that of space-time itself. Consequently, as well as being an ideal analogue for almost everything in condensed matter physics, superfluid helium-3 can be used to simulate particle and cosmic phenomena such as black holes and cosmic strings.

Rich Haley is responsible for a program of ultra-low temperature superfluid helium-3 experiments on phase transitions and nucleation which have fundamental implications across all science. He is also involved in group work that includes the study of turbulence in helium-3 and helium-4, and new refrigeration techniques to push the limits of the lowest achievable temperatures.

Rich gained his doctorate at the University of Manchester, working on the magnetic and textural properties of the A phase of superfluid helium-3. He then spent two years at the University of Florida making ultra-low temperature NMR and pressure measurements on solid mixtures of helium-3 in helium-4. He returned to the UK at the end of 1997 to take up a postdoc in the Lancaster ULT group.

In 2002 Rich was awarded a Royal Society University Research Fellowship, extended to 2010. He is now a Reader in Low Temperature Physics.
