Realizations of the Yang-Poisson model on canonical phase space

S. Meljanac, S. Mignemi

We discuss exact realizations of the Yang-Poisson model on canonical phase space. The Yang model is an example of noncommutative geometry on a background spacetime of constant curv…

Shadows of new physics on Dirac materials, analog GUPs and other amusements

Alfredo Iorio, Boris Ivetić, Salvatore Mignemi +1

We discuss here how, when higher-order effects in the parameter , related to the lattice spacing , are considered, pristine graphene, and other…

Quantum perturbative solutions of extended Snyder and Yang models with spontaneous symmetry breaking

Jerzy Lukierski, Stjepan Meljanac, Salvatore Mignemi +1

We propose -expansions as perturbative solutions of quantum extended Snyder and Yang models, with -independent classical zero-th order terms responsible for the spont…

Noncommutative Yang model and its generalizations

S. Meljanac, S. Mignemi

Long time ago, C.N. Yang proposed a model of noncommutative spacetime that generalized the Snyder model to a curved background. In this paper we review his proposal and the general…

Quantum mechanics of the extended Snyder model

S. Meljanac, S. Mignemi

We investigate a quantum mechanical harmonic oscillator based on the extended Snyder model. This realization of the Snyder model is constructed as a quantum phase space generated b…

Generalized quantum phase spaces for the -deformed extended Snyder model

Jerzy Lukierski, Stjepan Meljanac, Salvatore Mignemi +1

We describe, in an algebraic way, the -deformed extended Snyder models, that depend on three parameters and , which in a suitable algebra basis are described by the de…
