Elementary excitations and heat capacity singularity in superfluid helium
V. B. Bobrov, S. A. Trigger
We proceed from the premise that the spectrum of elementary excitations in the normal component in Landau's theory of superfluidity should depend on the superfluid helium temperatu…
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…
On the Necessary Conditions for the Validity of the Hohenberg-Kohn Theorem
V. B. Bobrov, S. A. Trigger, G. J. F. van Heijst
It is shown that the Hohenberg-Kohn lemma and theorem are direct consequences of the statement that the ground state energy (or free energy) of a system of interacting particles in…
Finite Size Atom in the Hartree-Fock Approximation: New Substance Quasiparticle
V. B. Bobrov, S. A. Trigger
It is shown that, in the self-consistent quantum statistical Hartree-Fock approximation, the number of electronic states localized on one nucleus is finite. This result is obtained…
Density functional theory and free energy of inhomogeneous electron gas
V. B. Bobrov, S. A. Trigger
It is shown that in adiabatic approximation for nuclei the many-component Coulomb system cannot be described on the basis of the grand canonical ensemble. Using the variational Bog…
