Abstract The Generalized Uncertainty Principle (GUP) naturally emerges in several quantum gravity models, predicting the existence of a minimal length at Planck scale. Here, we consider quadratic GUP as semiclassical approach to thermodynamic and constrain deformation parameter by using observational bounds from Big Bang Nucleosynthesis primordial abundances light elements $${}^4 He, D, {}^7 Li...

The non-zero minimal length arises in various theories of gravity, leading to the so-called generalized uncertainty principle (GUP). In this short paper we analyze GUP effects on neutron interferometry, showing that obtained phase shifts depend mass and velocity particle. New upper bounds dimensionless parameter have been found are agreement with literature.

Many models of dark energy have been proposed to describe the universe since beginning Big Bang. In this study, we present a new model agegraphic based on three generalized uncertainty principles KMM (Kempf, Mangan, Mann), Nouicer and [Formula: see text] (higher orders principle). Using obtained relations from types Generalized Uncertainty Principle (GU P), in form scenarios (Emergent, Intermed...
