Constraining Snyder and GUP models with low-mass stars
Pachol, Anna; Wojnar, Aneta (Peer reviewed; Journal article, 2023)We investigate the application of an equation of state that incorporates corrections derived from the Snyder model (and the Generalized Uncertainty Principle) to describe the behaviour of matter in a low-mass star. Remarkably, ... -
Fermi equation of state with finite temperature corrections in quantum space-times approach: Snyder model vs GUP case
Pachol, Anna; Wojnar, Aneta (Peer reviewed; Journal article, 2023)We investigate the impact of the deformed phase space associated with the quantum Snyder space on microphysical systems. The general Fermi–Dirac equation of state and specific corrections to it are derived. We put emphasis ... -
Generalized quantum phase spaces for the κ-deformed extended Snyder model
Lukierski, Jerzy; Meljanac, Stjepan; Mignemi, Salvatore; Pachol, Anna (Peer reviewed; Journal article, 2023)We describe, in an algebraic way, the κ-deformed extended Snyder models, that depend on three parameters β, κ and λ, which in a suitable algebra basis are described by the de Sitter algebras o(1, N). The commutation relations ... -
Quantum perturbative solutions of extended Snyder and Yang models with spontaneous symmetry breaking
Lukierski, Jerzy; Meljanac, Stjepan; Mignemi, Salvatore; Pachol, Anna (Peer reviewed; Journal article, 2023)We propose ħ-expansions as perturbative solutions of quantum extended Snyder and Yang models, with ħ-independent classical zero-th order terms responsible for the spontaneous breaking D = 4 and D = 5 de Sitter symmetries. ... -
ℏ -perturbative solutions of quantum Snyder and Yang models with parameters describing spontaneous symmetry breaking
Lukierski, Jerzy; Pachol, Anna (Peer reviewed; Journal article, 2023)We introduce the perturbative ℏ-power series (ℏ - Planck constant) providing the algebraic solutions of D=4 quantum Snyder and Yang models which describe relativistic quantum space-times and Lorentz-covariant quantum phase ...
