Axionlike dark-matter winds driven by galactic baryon redistribution
A. V. Nazarenko
We examine solutions of the hydrodynamic equations for dark matter (DM) modeled as a Bose-Einstein condensate (BEC) with axionlike interaction, forming a spherically symmetric halo…
Axionlike Dark Matter Model Involving Two-Phase Structure and Two-Particle Composites (Dimers)
A. M. Gavrilik, A. V. Nazarenko
Within the self-gravitating Bose-Einstein condensate (BEC) model of dark matter (DM), we argue that the axionlike self-interaction of ultralight bosons ensures the existence of bot…
New Deformed Heisenberg Algebra from the -Deformed Model of Dark Matter
A. M. Gavrilik, I. I. Kachurik, A. V. Nazarenko
Recently, the -deformation-based approach to modeling dark matter, which exploits -deformed thermodynamics, was extended to the study of galaxy halo density profile and of th…
Formation of Dimers in Axion-Like Dark Matter Using the Feshbach Resonance
A. M. Gavrilik, A. V. Nazarenko
Within the model of self-gravitating Bose--Einstein condensate (BEC) dark matter (DM) it is argued that the axion-like self-interaction of ultralight bosons provides the existence…
Phases of the Bose-Einstein condensate dark matter model with both two- and three-particle interactions
A. M. Gavrilik, A. V. Nazarenko
In this paper we further elaborate on the Bose-Einstein condensate (BEC) dark matter model extended in our preceding work [Phys. Rev. D 102, 083510 (2020)] by the inclusion of 6th…
Bose-Einstein condensate dark matter model with three-particle interaction and two-phase structure
A. M. Gavrilik, M. V. Khelashvili, A. V. Nazarenko
We explore the consequences of including the repulsive three-particle interaction in the model of Bose-Einstein condensate dark matter model or fuzzy dark matter. Such a model base…
Partition Function of the Bose-Einstein Condensed Dark Matter and the Modified Gross-Pitaevskii Equation
A. V. Nazarenko
Intending to describe the dark matter of dwarf galaxies, we concentrate on one model of the slowly rotating and gravitating Bose-Einstein condensate. For a deeper understanding of…
Statistics effects in extremal black holes ensemble
A. M. Gavrilik, A. V. Nazarenko
We consider the grand canonical ensemble of the static and extremal black holes, when the equivalence of the electric charge and mass of individual black hole is postulated. Assumi…
Photon Gas at the Planck Scale within the Doubly Special Relativity
W. S. Chung, A. M. Gavrilik, A. V. Nazarenko
Within the approach to doubly special relativity (DSR) suggested by Magueijo and Smolin, a new algebraically justified rule of so-called -addition for the energies of identical…
Condensate of -Bose gas as a model of dark matter
A. M. Gavrilik, I. I. Kachurik, M. V. Khelashvili +1
Though very popular, Bose-Einstein condensate models of dark matter have some difficulties. Here we propose the so-called -Bose gas model (-BGM) as a model of dark matter, ab…
The use of -Bose gas model for effective modeling of dark matter
A. M. Gavrilik, I. I. Kachurik, M. V. Khelashvili +1
For the recently introduced -deformed analog of Bose gas model (-Bose gas model), its thermodynamical aspects e.g. total number of particles and the partition function are ce…
Glasma Evolution in Partonic Medium
A. V. Nazarenko
We examine a scenario of the abelianized Glasma evolution with accounting for back-reaction of partonic medium in ultrarelativistic heavy-ion collisions. We announce that such a ge…
Probability of Creation of Extra Dimensions in Nuclear Collisions
A. V. Nazarenko
The minisuperspace model in spatial dimensions with the matter, described by the bag model, is considered with the aim to estimate the probability of creation of the compacti…
Liquid-like phases of π^+π^- matter
D. V. Anchishkin, A. V. Nazarenko
To give a common theoretical description of liquid phases of the charged pion matter in a wide temperature interval, the relativistic quantum type model is considered. The li…
