Research Interests

Research interests are focused on studies of collective order/disorder processes, quantum diffusion and defect formation in quantum solids and fluids. Current activites include: (1) Studies of order/disorder processes in solid hydrogen, diffusion of vacancies and isotopic impurities in solid H2, solid 3He and 4He. (2) NMR investigations of solids at very high magnetic fields with National High Magetic Field Laboratory and UF Microkelvin Laboratory. (3) Search for axions as candidates of galactic halo dark matter (in collaboration with David Tanner and Pierre Sikivie).
