Phase transition in a phonon gas with pair correlation
Yu. M. Poluektov
The phase transition to the state of a phonon gas with pairwise correlations of interacting phonons with opposite momenta is studies. A method for describing such phonon systems wi…
Nuclear and electronic coherence in superfluid helium
Yu. M. Poluektov
A semi-phenomenological model of a many-particle system of 4He atoms is proposed, in which a helium atom is considered as a complex consisting of a nucleus and a bound pair of elec…
Debye model for the surface phonons
Yu. M. Poluektov
A quantum description of the surface waves in an isotropic elastic body without the use of the semiclassical quantization is proposed. The problem about the surface waves is formul…
Accounting for the long-range forces in the model of hard sphere
Yu. M. Poluektov
A method for taking into account the long-range potential of atoms in the framework of the hard-sphere model is proposed. It is shown that thermodynamic quantities can be represent…
The two-parameter Debye model
Yu. M. Poluektov
When analyzing thermodynamic and kinetic properties of crystals whose anisotropy is not large and the considered effects do not relate to the existence of singled-out directions in…
Waves in a Bose-Einstein condensate of atoms with a dipole moment
Yu. M. Poluektov, A. A. Soroka
Based on the modified Gross-Pitaevskii equation for atoms with intrinsic dipole moments which accounts for the relaxation of a condensate, the dipole-dipole interaction and the int…
