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.

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.

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 ...

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 ...

Generalized entanglement entropy, charges, and intertwiners

open access: yesJournal of High Energy Physics, 2020
The entanglement theory in quantum systems with internal symmetries is rich due to the spontaneous creation of entangled pairs of charge/anti-charge particles at the entangling surface.

Poisson gauge models and Seiberg-Witten map

open access: yesJournal of High Energy Physics, 2022
The semiclassical limit of full non-commutative gauge theory is known as Poisson gauge theory. In this work we revise the construction of Poisson gauge theory paying attention to the geometric meaning of the structures involved and advance in the ...

Marginal and Relevant Deformations of N=4 Field Theories and Non-Commutative Moduli Spaces of Vacua [PDF]

open access: yes, 2000
We study marginal and relevant supersymmetric deformations of the N=4 super-Yang-Mills theory in four dimensions. Our primary innovation is the interpretation of the moduli spaces of vacua of these theories as non-commutative spaces.

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.

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.
