CALCULATIONS ON THE TEMPERATURE DEPENDENCE OF THE KNIGHT SHIFT IN LIQUID METALS AT CONSTANT VOLUME AND ITS MEASUREMENT IN SODIUM.

Abstract : The temperature dependence of the Knight shift in liquid metals at constant volume is investigated theoretically on the basis of the nearly-free-electron model. A comparison is made of the theoretical value with the experimental value determined here for sodium. The ratio of the temperature coefficients of the liquid and solid state is also discussed.

ELECTRON-PHONON INTERACTION AND CYCLOTRON RESONANCE IN METALS

The theory of electron-phonon interaction shifting of the cyclotron and thermal masses is extended to include a d-c magnetic field in Frohlichs Hamiltonian, obtaining the h-f conductivity. Landaus theory of Fermi liquids was applied to see the effect of the Coulomb interaction of electrons. (R.E.U.)

Transport coefficients of quantum plasma.

The two time Greens function method is applied to calculate the transport coefficients of an electron gas. The sequence of equations for Greens functions is derived. and it is shown that the results corresponding to the random phase approximation (including the exchange effects) can be obtained by terminating this sequence at the first stage. Proceeding to the second stage, one can quite naturally take the shielding effects and the plasma oscillation into account. Some discussions are made about the derivation of the kinetic equation for quantum plasma. (auth)

Effect of Coulomb Interaction on Anomalous Skin Effect

Many-body correlation effects on transport phenomena result from the self-energy effect described by the quasiparticle picture and from the two-body (electron-electron, hole-hole, or electron-hole) correlation effect that cannot be included in the one-particle picture. There is no correction in the extreme anomalous limit; ambiguity exists in the choice of the boundary condition. It is shown tha this ambiguity can be removed by calculating the frequency and wave number dependent conductivity sigma /sub omega / (q) (S. Nakajima, Progr. Theoret. Phys., 23: 694(1960)). The boundary condition is considered when the Maxwell equation coupled with the generalized Ohm law is solved. The general formula of conductivity and the method of Green functions are used.

Green Function Method in Quantum-Statistics

An extension is presented of the slightly refined Matsubara method for the computation of the grand partition function for quantum statistical averages. This computation is extended for the case of the electron gas, from which the results of Montroll and Ward are obtained. A slight
