Electric-magnetic Duality in Noncommutative Geometry [PDF]

open access: yes, 1997
The structure of S-duality in U(1) gauge theory on a 4-manifold M is examined using the formalism of noncommutative geometry. A noncommutative space is constructed from the algebra of Wilson-'t Hooft line operators which encodes both the ordinary ...

Tunnelling Mechanism in Noncommutative Space with Generalized Uncertainty Principle and Bohr-Like Black Hole

open access: yesAdvances in High Energy Physics, 2018
The paper deals with nonthermal radiation spectrum by tunnelling mechanism with correction due to the generalized uncertainty principle (GUP) in the background of noncommutative geometry.

Holographic thermalization in noncommutative geometry

open access: yesPhysics Letters B, 2015
Gravitational collapse of a shell of dust in noncommutative geometry is probed by the renormalized geodesic length, which is dual to probe the thermalization by the two-point correlation function in the dual conformal field theory.

Quantum Spacetime, Noncommutative Geometry and Observers

open access: yesUniverse, 2021
I discuss some issues related to the noncommutative spaces κ and its angular variant ρ-Minkowski with particular emphasis on the role of observers.

Electrodynamics from noncommutative geometry [PDF]

open access: yesJournal of Noncommutative Geometry, 2013
Within the framework of Connes’ noncommutative geometry, the notion of an almost commutative manifold can be used to describe field theories on compact Riemannian spin manifolds. The most notable example is the derivation of the Standard Model of high energy physics from a suitably chosen almost commutative manifold.

External Fields as Intrinsic Geometry [PDF]

open access: yes, 2000
There is an interesting dichotomy between a space-time metric considered as external field in a flat background and the same considered as an intrinsic part of the geometry of space-time.

Nonlinear connections and spinor geometry

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We present an introduction to the geometry of higher-order vector and covector bundles (including higher-order generalizations of the Finsler geometry and Kaluza-Klein gravity) and review the basic results on Clifford and spinor structures on spaces ...

Noncommutative Schwarzschild geometry and generalized uncertainty principle

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We discuss a possible link between the deformation parameter $$\Theta ^{\mu \nu }$$ Θμν arising in the framework of noncommutative geometry and the parameter $$\beta $$ β of the generalized uncertainty principle (GUP). We compute the shift of the Hawking

Spectral Triples in Particle Physics

open access: yesEPJ Web of Conferences, 2018
We give an overview of the approach to the Standard Model of Particle Physics and its extensions based on the Noncommutative Geometry. The notion of spectral triples is introduced and their applications in particle physics are presented. We revisit known
