Thermodynamics of high order correction for Schwarzschild-AdS black hole in non-commutative geometry

open access: yesNuclear Physics B
Under the premise that quantum gravity becomes non-negligible, higher-order corrections of non-commutative geometry dominate. In this paper, we studied the thermodynamics of high-order corrections for Schwarzschild-AdS black hole with Lorentz ...

Quasi-Homogeneous Black Hole Thermodynamics in Non-Commutative Geometry

open access: yesUniverse
We study the thermodynamic properties of a black hole that takes into account the effects of non-commutative geometry. To emphasize the role of new effects, we have chosen a specific modified Schwarzschild black hole inspired by non-commutative geometry.

Second moment fuzzy-field-theory-like matrix models

open access: yesJournal of High Energy Physics, 2020
We solve a multitrace matrix model approximating the real quartic scalar field theory on the fuzzy sphere and obtain its phase diagram. We generalize this method to models with modified kinetic terms and demonstrate its use by investigating models ...

Gravity in Non-Commutative Geometry [PDF]

open access: yes, 1992
We study general relativity in the framework of non-commutative differential geometry. In particular, we introduce a gravity action for a space-time which is the product of a four dimensional manifold by a two-point space.

The multitrace matrix model: An alternative to Connes NCG and IKKT model in 2 dimensions

open access: yesPhysics Letters B, 2016
We present a new multitrace matrix model, which is a generalization of the real quartic one matrix model, exhibiting dynamical emergence of a fuzzy two-sphere and its non-commutative gauge theory.

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 ...

Resolution of Stringy Singularities by Non-commutative Algebras [PDF]

open access: yes, 2001
In this paper we propose a unified approach to (topological) string theory on certain singular spaces in their large volume limit. The approach exploits the non-commutative structure of D-branes, so the space is described by an algebraic geometry of non ...

Lie-Poisson gauge theories and κ-Minkowski electrodynamics

open access: yesJournal of High Energy Physics, 2023
We consider gauge theories on Poisson manifolds emerging as semiclassical approximations of noncommutative spacetime with Lie algebra type noncommutativity.

Linear Connections in Non-Commutative Geometry [PDF]

open access: yes, 1994
A construction is proposed for linear connections on non-commutative algebras. The construction relies on a generalisation of the Leibnitz rules of commutative geometry and uses the bimodule structure of $\Omega^1$.
