Braided quantum electrodynamics

open access: yesJournal of High Energy Physics, 2023
The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

κ-Minkowski-deformation of U(1) gauge theory

open access: yesJournal of High Energy Physics, 2021
We construct a noncommutative kappa-Minkowski deformation of U(1) gauge theory, following a general approach, recently proposed in JHEP 08 (2020) 041.

Operads and Γ-homology of commutative rings [PDF]

open access: yes, 2002
We introduce Γ-homology, the natural homology theory for E[infty infinity]-algebras, and a cyclic version of it. Γ-homology specializes to a new homology theory for discrete commutative rings, very different in general from André–Quillen homology.

Entanglement entropy on a fuzzy sphere with a UV cutoff

open access: yesJournal of High Energy Physics, 2018
We introduce a UV cutoff into free scalar field theory on the noncommutative (fuzzy) two-sphere. Due to the IR-UV connection, varying the UV cutoff allows us to control the effective nonlocality scale of the theory.

Beyond second-moment approximation in fuzzy-field-theory-like matrix models

open access: yesJournal of High Energy Physics, 2022
We investigate the phase structure of a special class of multi-trace hermitian matrix models, which are candidates for the description of scalar field theory on fuzzy spaces.

Introduction to Non Commutative Algebraic Geometry [PDF]

open access: yes, 2015
Ordinary commutative algebraic geometry is based on commutative polynomial algebras over an algebraically closed field k. Here we make a natural generalization to matrix polynomial k-algebras which are non-commutative coordinate rings of non-commutative ...

Detecting scaling in phase transitions on the truncated Heisenberg algebra

open access: yesJournal of High Energy Physics, 2021
We construct and analyze a phase diagram of a self-interacting matrix field coupled to curvature of the non-commutative truncated Heisenberg space. The model reduces to the renormalizable Grosse-Wulkenhaar model in an infinite matrix size limit and ...

Non-commutative geometry, non-associative geometry and the standard model of particle physics

open access: yesNew Journal of Physics, 2014
Connes’ notion of non-commutative geometry (NCG) generalizes Riemannian geometry and yields a striking reinterepretation of the standard model of particle physics, coupled to Einstein gravity.

Time dependence of entanglement entropy on the fuzzy sphere

open access: yesJournal of High Energy Physics, 2017
We numerically study the behaviour of entanglement entropy for a free scalar field on the noncommutative (“fuzzy”) sphere after a mass quench. It is known that the entanglement entropy before a quench violates the usual area law due to the non-local ...
