A theoretical condensed matter physicist who coauthored a dilute-magnon description of field-induced ordering in . Its mean-field theory connected the measured magnetization to Bose-Einstein condensation. The magnetic field permits the excitation population to vary, providing a grand canonical ensemble setting for condensation physics.[ref]
