From the density functional to the single-particle Green function
V. B. Bobrov
An analysis shows that the ground state of the inhomogeneous system of interacting electrons in the static external field, which satisfies the thermodynamic limit, can be consisten…
Virial theorem and Gibbs thermodynamic potential for Coulomb systems
V. B. Bobrov, S. A. Trigger
Using the grand canonical ensemble and the virial theorem, we show that the Gibbs thermodynamic potential of the non-relativistic system of charged particles is uniquely defined by…
Metal - non-metal transition and the second critical point in expanded metals
V. B. Bobrov, S. A. Trigger, A. G. Zagorodny
Based on the non-relativistic Coulomb model within which the matter is a system of interacting electrons and nuclei, using the quantum field theory and linear response theory metho…
Theory of degenerate Bose gas without anomalous averages
V. B. Bobrov, S. A. Trigger
Theory of a weakly non-ideal Bose gas in the canonical ensemble is developed without assumption of the C-number representation of the creation and annihilation operators with zero…
Ground state energy in the external field and the problem of density functional approximations
V. B. Bobrov, S. A. Trigger
Based on the Schrodinger equation, exact expressions for the non-relativistic particle energy in the local external field and the external field potential are derived as inhomogene…
Exact Density Functional for the Non-Relativistic Particle Energy in the Local External Field
V. B. Bobrov, S. A. Trigger
Based on the Schrodinger equation, exact expressions for the non-relativistic particle energy in the local external field and the external field potential are derived as inhomogene…
