Galaxy rotation curves in the -deformation based approach to dark matter
A. M. Gavrilik, I. I. Kachurik, M. V. Khelashvili
We elaborate further the -deformation-based approach to modeling dark matter, in addition to the earlier proposed use of -deformed thermodynamics. Herein, we construct -de…
Pseudo-Hermitian position and momentum operators, Hermitian Hamiltonian, and deformed oscillators
A. M. Gavrilik, I. I. Kachurik
The recently introduced by us two- and three-parameter ()- and ()-deformed extensions of the Heisenberg algebra were explored under the condition of their direct link w…
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…
Baryon Decuplet Masses From the Viewpoint of q-Equidistance
A. M. Gavrilik, I. I. Kachurik, A. V. Tertychnyj
Masses of baryons {3/2}^+ are calculated on the base of representations of dynamical "pseudounitary" q-deformed algebra u(4,1)_q which provides necessary breaking of the 4-flavor s…
