Quasiparticle Damping of Surface Waves in Superfluid ${}^3$He and ${}^4$He

Matti S. Manninen, Juho Rysti, Igor Todoshchenko +1

Oscillations on free surface of superfluids at the inviscid limit are damped by quasiparticle scattering. We have studied this effect in both superfluids ${}^3$He and ${}^4$He deep bel…
