Classical and quantum mechanics of the nonrelativistic Snyder model

S Mignemi - Physical Review D—Particles, Fields, Gravitation, and …, 2011 - APS
The Snyder model is an example of noncommutative spacetime admitting a fundamental
length scale β and invariant under Lorentz transformations, that can be interpreted as a …

Classical and quantum mechanics of the nonrelativistic Snyder model in curved space

S Mignemi - Classical and Quantum Gravity, 2012 - iopscience.iop.org
Abstract The Snyder–de Sitter (SdS) model is a generalization of the Snyder model to a
spacetime background of constant curvature. It is an example of noncommutative spacetime …

[HTML][HTML] Noncommutative Yang model and its generalizations

S Meljanac, S Mignemi - Journal of Mathematical Physics, 2023 - pubs.aip.org
Long time ago, Yang [Phys. Rev. 72, 874 (1947)] proposed a model of noncommutative
spacetime that generalized the Snyder model to a curved background. In this paper, we …

Deformed symmetry in Snyder space and relativistic particle dynamics

R Banerjee, S Kulkarni, S Samanta - Journal of High Energy …, 2006 - iopscience.iop.org
We describe the deformed Poincaré-conformal symmetries implying the covariance of the
noncommutative space obeying Snyder's algebra. Relativistic particle models invariant …

Worldline formalism in Snyder spaces

SA Franchino-Viñas, S Mignemi - Physical Review D, 2018 - APS
We study the ϕ⋆ 4 model for a scalar field in a linearization of the Snyder model, using the
methods of the worldline formalism. Our main result is a master equation for the 1-loop n …

[HTML][HTML] Snyder space revisited

L Lu, A Stern - Nuclear Physics B, 2012 - Elsevier
We examine basis functions on momentum space for the three-dimensional Euclidean
Snyder algebra. We argue that the momentum space is isomorphic to the SO (3) group …

Particle dynamics on Snyder space

L Lu, A Stern - Nuclear Physics B, 2012 - Elsevier
We examine Hamiltonian formalism on Euclidean Snyder space. The latter corresponds to a
lattice in the quantum theory. For any given dynamical system, it may not be possible to …

Snyder dynamics in a Schwarzschild spacetime

S Mignemi, R Štrajn - Physical Review D, 2014 - APS
We calculate the orbits of a particle in Schwarzschild spacetime, assuming that the dynamics
is governed by a Snyder symplectic structure. With this assumption, the perihelion shift of the …

Relative-locality phenomenology on Snyder spacetime

S Mignemi, G Rosati - Classical and Quantum Gravity, 2018 - iopscience.iop.org
We study the effects of relative locality dynamics in the case of the Snyder model. Several
properties of this model differ from those of the widely studied models: for example, in the …

Quantum mechanics of the extended Snyder model

S Meljanac, S Mignemi - Symmetry, 2023 - mdpi.com
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 …
