Non-polarizing two-atom interaction potential in the liquid He-4
D. B. Baranov, V. S. Yarunin, A. I. Kirillov
A formula for potential U of the He-4--He-4 interaction in the liquid state is obtained by the direct electromagnetic computation as a function of the interatomic distance R. The p…
Two-atomic potential and distortion of excitation spectrum of liquid He-4 by admixture of He-3
D. B. Baranov, V. S. Yarunin, A. I. Kirillov
The new interatomic potential g(r), providing the tunnelling of atoms, is suggested for calculating HFB phonon-roton spectrum E(p) of liquid He-4. The tunnelling enables the calcul…
Odd-odd Magnetic Interaction and Spontaneous Ortho-para Transitions in Molecule and Molecular Hydrogen Ion
V. S. Yarunin
Spontaneous nuclear ortho-para transitions are shown to be possible in hydrogen molecule and molecular ion as due to hyperfine interaction odd-odd relative to the space or spin nuc…
He-4 spectrum shift caused by He-3 admixture
D. Baranov, V. Yarunin
The shift of a maxon-roton He-4 excitation spectrum E via the He-3 admixture is considered theoretically. The Bogoliubov formula for E(ρ, g) as a function of Bose-condensate densit…
Trapped Bose-condensate in gravity field
D. B. Baranov, V. S. Yarunin
The 1D and 2D Bose-condensation of trapped atoms in a gravitational field are considered. The deformation of the finite parabolic potential in this field is modeling via the combin…
On representation of the t-J model via spin-charge variables
Evgueni Kochetov, Vladimir Yarunin
We show that the t-J Hamiltonian is not in general reduced to H(S,f), where S and f stand for independent ([S,f]=0) SU(2) (spin) generators and spinless fermionic (hole) field, res…
