A new approach is proposed to calculate the thermodynamic potential, which consists in reducing the relevant non-Gaussian functional integral to its Gaussian form with a renormalized “density-density” correlator. It ...

Energy of electronic subsystem of semi-infinite metal is presented in the form of an expansion in powers of pseudo-potential. It is shown that generally electron many-particle density matrices are necessary for the energy ...

Viscoelastic description of the electron subsystem of a semi-bounded metal on the basis of the generalized "jellium" model using the method of nonequilibrium statistical Zubarev operator is proposed. The nonequilibrium ...
