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.

Pseudo-Riemannian structures in Pati-Salam models

open access: yesJournal of High Energy Physics, 2020
We discuss the role of the pseudo-Riemannian structure of the finite spectral triple for the family of Pati-Salam models. We argue that its existence is a very restrictive condition that separates leptons from quarks, and restricts the whole family of ...

Poisson gauge theory

open access: yesJournal of High Energy Physics, 2021
The Poisson gauge algebra is a semi-classical limit of complete non- commutative gauge algebra. In the present work we formulate the Poisson gauge theory which is a dynamical field theoretical model having the Poisson gauge algebra as a corresponding ...

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.

Differential algebras in non-commutative geometry [PDF]

open access: yesJournal of Geometry and Physics, 1995
We discuss the differential algebras used in Connes' approach to Yang-Mills theories with spontaneous symmetry breaking. These differential algebras generated by algebras of the form functions $\otimes$ matrix are shown to be skew tensorproducts of differential forms with a specific matrix algebra.

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 ...

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.

On tea, donuts and non-commutative geometry [PDF]

open access: yesSurveys in Mathematics and its Applications, 2018
As many will agree, it feels good to complement a cup of tea by a donut or two. This sweet relationship is also a guiding principle of non-commutative geometry known as Serre Theorem.

Monopole star products are non-alternative

open access: yesJournal of High Energy Physics, 2017
Non-associative algebras appear in some quantum-mechanical systems, for instance if a charged particle in a distribution of magnetic monopoles is considered.
