Missing the point in noncommutative geometry. [PDF]

open access: yesSynthese, 2021
Noncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area.

Noncommutative geometry of Zitterbewegung [PDF]

open access: goldPhysical Review D, 2017
Drawing from the advanced mathematics of noncommutative geometry, we model a ``classical'' Dirac fermion propagating in a curved spacetime. We demonstrate that the inherent causal structure of the model encodes the possibility of Zitterbewegung---the ...

Stratified Noncommutative Geometry [PDF]

open access: yesMemoirs of the American Mathematical Society, 2019
We introduce a theory of stratifications of noncommutative stacks (i.e., presentable stable ∞ \infty -categories), and we prove a reconstruction theorem that expresses them in terms of their strata and gluing data. This reconstruction theorem is

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

Noncommutative geometry inspired black holes in Rastall gravity [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
Under two different metric ansatzes, the noncommutative geometry inspired black holes (NCBH) in the framework of Rastall gravity are derived and analyzed. We consider the fluid-type matter with the Gaussian-distribution smeared mass density.

B-decay anomalies and scalar leptoquarks in unified Pati-Salam models from noncommutative geometry [PDF]

open access: yesJournal of High Energy Physics, 2018
Motivated by possible scalar-leptoquark explanations of the recently reported B-decay anomalies, we investigate whether the required leptoquarks can be accommodated within models based on noncommutative geometry (NCG).

Curvature in noncommutative geometry [PDF]

open access: yesAdvances in Noncommutative Geometry, 2019
Our understanding of the notion of curvature in a noncommutative setting has progressed substantially in the past 10 years. This new episode in noncommutative geometry started when a Gauss-Bonnet theorem was proved by Connes and Tretkoff for a curved ...

Noncommutative coarse geometry [PDF]

open access: greenJournal of Noncommutative Geometry, 2019
We use compactifications of C*-algebras to introduce noncommutative coarse geometry. We transfer a noncommutative coarse structure on a C*-algebra with an action of a locally compact Abelian group by translations to Rieffel deformations and prove that the resulting noncommutative coarse spaces are coarsely equivalent.

The Geometry of Noncommutative Space-Time [PDF]

open access: green, 2016
Stabilization, by deformation, of the Poincaré-Heisenberg algebra requires both the introduction of a fundamental lentgh and the noncommutativity of translations which is associated to the gravitational field.
