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. We have also begun refining other Uranium-based superconductors.
Man Nguyen uses Cryo 1 to study the elementary excitations present in superfluid 3He. Ultrasonic sound waves are used to find topological excitations like Majorana fermions that live near the boundary of the superfluid.
John Scott has recently joined the ULT group and is working with Andrew on Cryo 2.
