Viscosity and ultrasonic attenuation in ⁴He below 0.6 K
Through a treatment of three-phonon processes, the wide-angle scattering rates and the absorption rates of phonons, which characterize viscosity and ultrasonic attenuation, respectively, are calculated for ⁴He below 0.6 K. These rates are obtained from the collision matrix which is constructed appro...
