New Deformed Heisenberg Algebra from the $\mu$-Deformed Model of Dark Matter

Abstract

Recently, the $\mu$-deformation-based approach to modeling dark matter, which exploits $\mu$-deformed thermodynamics, was extended to the study of galaxy halo density profile and of the rotation curves of a number of (dwarf or low brightness) galaxies. For that goal, $\mu$-deformed analogs of the Lane--Emden equation (LEE) have been proposed, and their solutions describing density profiles obtained. There are two seemingly different versions of $\mu$-deformed LEE which possess the same solution, and so we deal with their equivalence. From the latter property we derive new, rather unusual, $\mu$-deformed Heisenberg algebra (HA) for the position and momentum operators, and present the $\mu$-HA in few possible forms (each one at $\mu \to 0$ recovers usual HA). The generalized uncertainty relation linked with the new $\mu$-HA is studied, along with its interesting implications including the appearance of the quadruple of both maximal and minimal lengths and momenta.
