Multipole degrees of freedom in physics of high-spin quantum atomic gases
Autor: M. S. Bulakhov, Yu. V. Slyusarenko, A. S. Peletminskii
Publikováno v: Low Temperature Physics. 47:700-712
We provide the general arguments that quantum atomic gases of interacting high-spin atoms represent a physical system in which the multipole (hidden) degrees of freedom may be manifested. Their manifestation occurs when the interatomic interaction is

Broken-axisymmetry state and magnetic state diagram of spin-1 condensate through the prism of quadrupole degrees of freedom
Autor: M Bulakhov, A S Peletminskii, S V Peletminskii, Yu V Slyusarenko
We theoretically study a weakly interacting gas of spin-1 atoms with Bose-Einstein condensate in external magnetic field within the Bogoliubov approach. To this end, in contrast to previous studies, we employ the general Hamiltonian, which includes b

Aspects of Bose-Einstein condensation in a charged boson system over the dielectric surface
Autor: Andrii Sotnikov, I.V. Lukin, Yu. V. Slyusarenko
We study theoretically a gas consisting of charged bosons (ions) over the flat dielectric surface at low temperatures and its tendency to form a state with a Bose-Einstein condensate. For the stability of a system, an additional external electric fie

Kinetics of low-temperature gas of hydrogen-like atoms in an external electromagnetic field
Autor: А. G. Zagorodny, Yu. V. Slyusarenko, S. N. Shul'ga
Publikováno v: Low Temperature Physics. 44:1049-1061
A microscopic approach for the construction of the kinetic theory of low-temperature hydrogen-like gases in an external electromagnetic field was developed. The approach is based on the formulation of secondary quantization in the presence of bound s

Chemical potentials and thermodynamic characteristics of ideal Bose- and Fermi-gases in the region of quantum degeneracy
Autor: K. V. Sereda, Andrii Sotnikov, Yu. V. Slyusarenko
Publikováno v: Low Temperature Physics. 43:144-151
Calculations of chemical potentials for ideal monatomic gases with Bose-Einstein and Fermi-Dirac statistics as functions of temperature, across the temperature region that is typical for the collective quantum degeneracy effect, are presented. Numeri

Magnetic phases and phase diagram of spin-1 condensate with quadrupole degrees of freedom
Autor: Yu. V. Slyusarenko, S. V. Peletminskii, M. S. Bulakhov, A. S. Peletminskii
Publikováno v: Journal of Physics A: Mathematical and Theoretical. 54:165001
We obtain and justify a many-body Hamiltonian of pairwise interacting spin-1 atoms, which includes eight generators of the SU(3) group associated with spin and quadrupole degrees of freedom. It is shown that this Hamiltonian is valid for non-local in

Thermodynamics of a weakly interacting Bose gas above the transition temperature
Autor: Andrii Sotnikov, M. S. Bulakhov, A. S. Peletminskii, Yu. V. Slyusarenko
Publikováno v: Physica Scripta. 96:045401
We study thermodynamic properties of weakly interacting Bose gases above the transition temperature of Bose-Einstein condensation in the framework of a thermodynamic perturbation theory. Cases of local and non-local interactions between particles are
