Abstract

At zero temperature, orbital waves propagate in

{}^{3}{He}

-

A

with a dispersion relation

ω = q_{z} v_{F}

in the regime

\frac{{T_{c}}^{2}}{E_{F}} ≪ ℏ ω ≪ T_{c}

; the damping is also studied. In the regime

ℏ ω ≪ \frac{{T_{c}}^{2}}{E_{F}}

, undamped orbital waves propagate with the dispersion relation

ω \sim (\frac{E_{F}}{{T_{c}}^{2}}) {(q_{z} v_{F})}^{2} \ln (\frac{T_{c}}{q_{z} v_{F}})

.
