Abstract

A relation is established between the Fermi excitation energies predicted by the Landau theory of the Fermi fluid and by many-particle quantum theory at zero temperature. (auth)

THEORY OF FERMI FLUID

B.T. Geilikman

The ground state energy and other characteristics of a Fermi system are calculated by employing the Green function method and theory of Fermi fluids. The calculations are carried out for long range and short range potential components such that n/sup 1/3/ r/sub s/ > 1 where r/ sub s/ and r/sub l/ are the ranges of action of the short- and long-range force components and n is the particle density.

SPECTRUM OF ELEMENTARY EXCITATIONS OF SUPER-FLUID FERMI SYSTEMS

I.I. Krush, Yu.V. Tsekhmistrenko

A number of problems involving the spectrum of elementary excitations of superfluid Fermi systems were studied by the methods of quantum field theory. A system with direct binary interaction is considered at zero and non-zero temperature, as well as an electron-phonon system at absolute zero. On finding Schwinger's equations for oneparticle Greene functions, use was made of the ground state approximation proposed by N. N. Bogoliubov, i.e., a formalism was applied which does not preserve the full number of particles. (auth)
