Einstein crystals in Snyder and Snyder-de Sitter noncommutative backgrounds
Anna PachoÅ, Aneta Wojnar
We investigate the behavior of Einstein crystals in noncommutative backgrounds described by the Snyder and Snyder-de Sitter models. Possible novel effects, which may arise in reali…
Refining Bounds for Snyder and GUP Models through Seismic Wave Analysis
Aleksander Kozak, Anna PachoÅ, Aneta Wojnar
This study investigates possibility of placing bounds on the parameters, arising from the non-commutative Snyder space-time model and Generalized Uncertainty Principle (GUP) approa…
Towards new relativistic doubly -deformed D=4 quantum phase spaces
Jerzy Lukierski, Stjepan Meljanac, Salvatore Mignemi +2
We propose new noncommutative models of quantum phase spaces, containing a pair of -deformed Poincaré algebras, with two independent double ()-deformations in spa…
Generalized Extended Uncertainty Principles, Liouville theorem and density of states: Snyder-de Sitter and Yang models
A. PachoÅ
Modifications in quantum mechanical phase space lead to the changes in the Heisenberg uncertainty principle, which can result in the Generalized Uncertainty Principle (GUP) or the…
