“…In the former case four-photon processes (4PP) are dominant, while in the latter case 3PP become important. 2 Andreev and Khalatnikov 3 calculated the temperature variation of sound in bulk liquid helium using a collisionless kinetic equation together with an equation for the superfluid velocity. Singh and Prakash 4 investigated the behavior of the retarded single-particle Green's function for a weakly-interacting Bose gas and found a new temperaturedependent term.…”
