Andrew Zimmerman studies superfluid 3He in aerogel on Cryo 2 . In particular, he is using Nuclear Magnetic Resonance (NMR) to investigate the interplay between structural anisotropy of the aerogel and superfluid phase stability and textures.

Keenan Avers runs the Uranium-Platinum3 (UPt3) crystal growth lab and studies its superconducting properties using small-angle neutron scattering.

Man Nguyen uses Cryo 1 to study the elementary excitations present in superfluid 3He. The properties of a many-fermion system are usually described by either "dressed" versions of the constituent fermions or by bosonic collective excitations that behave vastly differently. One unique property of 3He is that it supports transverse acoustic sound waves, unlike any other known fluid. The bosonic excitations couple to these waves allowing us to probe the superfluid state.
