First sound velocity in liquid ⁴He
Based on the many-boson system structure factor, which takes into account three- and four-particle direct correlations, there was found the first sound velocity temperature behaviour in liquid ⁴He in the post-RPA approximation. The expression received for the sound velocity matches with the well-kno...
