Noncommutative field theories on $R_{λ}^{3}$ : Towards UV/IR mixing freedom

Patrizia Vitale, Jean-Christophe Wallet

We consider the noncommutative space $R_{λ}^{3}$ , a deformation of the algebra of functions on $R^{3}$ which yields a "foliation" of $R^{3}$ into fuzzy spheres.…

On the $⋆$ -product quantization and the Duflo map in three dimensions

Luigi Rosa, Patrizia Vitale

We analyze the star product induced on the algebra of functions on R^3 by a suitable reduction of the Moyal product defined on F(R^4). This is obtained through the identification o…

Higgs-Dilaton Lagrangian from Spectral Regularization

M. A. Kurkov, Fedele Lizzi

In this letter we calculate the full Higgs-Dilaton action describing the Weyl anomaly using the bosonic spectral action. This completes the work we started in our previous paper (J…

Exact charged black-hole solutions in D-dimensional f(T) gravity: torsion vs curvature analysis

Salvatore Capozziello, P. A. Gonzalez, Emmanuel N. Saridakis +1

We extract exact charged black-hole solutions with flat transverse sections in the framework of D-dimensional Maxwell-f(T) gravity, and we analyze the singularities and horizons ba…

Casimir energy for a spherical boundary within the surface impedance approach: Obtaining negative values

Luigi Rosa

We compute the Casimir Energy of a spherical region using a Surface Impedance approach. We characterize the Surface Impedance of the boundary using plasma model. Exact analytical f…

Noncommutative Field Theory: Numerical Analysis with the Fuzzy Disc

Fedele Lizzi, Bernardino Spisso

The fuzzy disc is a discretization of the algebra of functions on the two dimensional disc using finite matrices which preserves the action of the rotation group. We define a $φ^{4}$ …

More About Branes on a General Magnetized Torus

L. De Angelis, R. Marotta, F. Pezzella +1

In the framework of low-energy effective actions of branes compactified on magnetized extra-dimensions, we determine Yukawa couplings for the chiral matter described by open string…

Aspects of Group Field Theory

Patrizia Vitale

I review the basic ingredients of discretized gravity which motivate the introduction of Group Field Theory. Thus I describe the GFT formulation of some models and conclude with a…

Spectral methods in quantum field theory and quantum cosmology

Giampiero Esposito, Guglielmo Fucci, Alexander Yu. Kamenshchik +1

We review the application of the spectral zeta-function to the 1- loop properties of quantum field theories on manifolds with boundary, with emphasis on Euclidean quantum gravity a…

Gauge and Poincare' Invariant Regularization and Hopf Symmetries

Fedele Lizzi, Patrizia Vitale

We consider the regularization of a gauge quantum field theory following a modification of the Polchinski proof based on the introduction of a cutoff function. We work with a Poinc…
