Collective Modes and f-Wave Pairing Interactions in Superfluid 3He

  • 1. Department of Physics and Astronomy, Northwestern University, Evanston, Illinois 60208 (United States)

Description

Precision measurements of collective mode frequencies in superfluid 3He-B are sensitive to quasiparticle and f-wave pairing interactions. Measurements were performed at various pressures using interference of transverse sound in an acoustic cavity. We fit the measured collective mode frequencies, which depend on the strength of f-wave pairing and the Fermi liquid parameter F2s, to theoretical predictions and discuss what implications these values have for observing new order parameter collective modes
