Method of canonical transformations in the theory of quantum gases interacting with radiation
M. S. Bulakhov, A. S. Peletminskii, P. P. Kostrobij +2
An approach to the theoretical study of effects and phenomena in quantum gases interacting with radiation is proposed. The approach is based on a modification of the canonical tran…
Self-consistent Hartree-Fock-Bogoliubov approach for bosons: self-eliminating divergence and pure pair condensate
M. Bulakhov, A. S. Peletminskii
We investigate the thermodynamic properties of an interacting Bose gas with a condensate within the energy-functional formulation of the Hartree-Fock-Bogoliubov (HFB) approach. For…
General collisionless kinetic approach to studying excitations in arbitrary-spin quantum atomic gases
M. Bulakhov, A. S. Peletminskii, Yu. V. Slyusarenko
We develop a general kinetic approach to studying high-frequency collective excitations in arbitrary-spin quantum gases. To this end, we formulate a many-body Hamiltonian that incl…
Zero sound in a quantum gas of spin-3/2 atoms with multipole exchange interaction
M. Bulakhov, A. S. Peletminskii, Yu. V. Slyusarenko
In the context of quantum gases, we obtain a many-body Hamiltonian for spin-3/2 atoms with general multipole (spin, quadrupole, and octupole) exchange interaction by employing the…
Magnetic phases and phase diagram of spin-1 condensate with quadrupole degrees of freedom
M. S. Bulakhov, A. S. Peletminskii, S. V. Peletminskii +1
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 o…
Thermodynamics of a weakly interacting Bose gas above the transition temperature
M. S. Bulakhov, A. S. Peletminskii, Yu. V. Slyusarenko +1
We study thermodynamic properties of weakly interacting Bose gases above the transition temperature of Bose-Einstein condensation in the framework of a thermodynamic perturbation t…
Re-examining the quadratic approximation in theory of a weakly interacting Bose gas with condensate: the role of nonlocal interaction potentials
Mykyta Bulakhov, Alexander Peletminskii, Sergey Peletminskii +2
We derive and analyze the coupled equations of quadratic approximation of the Bogoliubov model for a weakly interacting Bose gas. The first equation determines the condensate densi…
