Green function formalism and superfluid properties of 4He
Description
The excitation spectrum of superfluid HeII is studied using the Lennard-Jones form of the potential and the reaction matrix of the Green's function method. The parameters of the theory are determined from the experimental data only. The results on energy values and equation of state amply justify the proposed philosophy. (author)
