Collective modes and f-wave pairing interactions in superfluid (3)He.
نویسندگان
چکیده
Precision measurements of collective mode frequencies in superfluid (3)He-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 F(2)(s), to theoretical predictions and discuss what implications these values have for observing new order parameter collective modes.

Magneto-acoustic rotation of transverse waves in He-B
In superfluid He-B, the off-resonant coupling of the J = 2−, M = ±1 order parameter collective modes to transverse current excitations stabilizes propagating transverse waves with low damping for frequencies above that of the J = 2− modes. Right(RCP) and left circularly polarized (LCP) transverse modes are degenerate in zero field; however, a magnetic field with H||q lifts this degeneracy givin...
متن کاملUnconventional symmetries of Fermi liquid and Cooper pairing properties with electric and magnetic dipolar fermions.
The rapid experimental progress of ultra-cold dipolar fermions opens up a whole new opportunity to investigate novel many-body physics of fermions. In this article, we review theoretical studies of the Fermi liquid theory and Cooper pairing instabilities of both electric and magnetic dipolar fermionic systems from the perspective of unconventional symmetries. When the electric dipole moments ar...

متن کاملDependence of the 1S0 superfluid pairing gap on nuclear interactions
Nucleon-nucleon (NN) interactions are well constrained for relative momenta k 2 fm−1 by existing scattering data [1]. The model dependences for larger momenta can be seen, for instance, in the P2 superfluid pairing gaps for Fermi momenta kF > 2 fm−1 [2]. In Ref. [3], we study in detail the dependence of the S0 superfluid gap on nuclear interactions at the BCS level, and on the resolution scale....
