$k$ -Minkowski-deformation of $U (1)$ gauge theory

V. G. Kupriyanov, M. Kurkov, P. Vitale

We construct a non-commutative kappa-Minkowski deformation of U(1) gauge theory, following a general approach, recently proposed in JHEP 2008 (2020) 041. We obtain an exact (all or…

Gravitons in a Casimir box

Francesco Alessio, Glenn Barnich, Martin Bonte

The partition function of gravitons with Casimir-type boundary conditions is worked out. The simplest box that allows one to achieve full analytical control consists of a slab geom…

The Weyl-Mellin quantization map for $κ$ -Minkowski Noncommutative Spacetime

Alessandro Carotenuto, Fedele Lizzi, Mattia Manfredonia +1

We present a quantization of the functions of spacetime, i.e.\ a map, analog to Weyl map, which reproduces the $κ$ -Minkowski commutation relations, and it has the desirable propert…

$κ$ -deformed complex fields and discrete symmetries

Michele Arzano, Andrea Bevilacqua, Jerzy Kowalski-Glikman +2

We present a construction of $κ$ -deformed complex scalar field theory with the objective of shedding light on the way discrete symmetries and CPT invariance are affected by the def…

Bekenstein bound and uncertainty relations

Luca Buoninfante, Giuseppe Gaetano Luciano, Luciano Petruzziello +1

The non zero value of Planck constant $h$ underlies the emergence of several inequalities that must be satisfied in the quantum realm, the most prominent one being Heisenberg Uncer…

Conformal Primary Basis for Dirac Spinors

Lorenzo Iacobacci, Wolfgang Mück

We study solutions to the Dirac equation in Minkowski space $R^{1, d + 1}$ that transform as $d$ -dimensional conformal primary spinors under the Lorentz group $S O (1, d + 1)$ . Su…

Jacobi sigma models

Francesco Bascone, Franco Pezzella, Patrizia Vitale

We introduce a two-dimensional sigma model associated with a Jacobi manifold. The model is a generalisation of a Poisson sigma model providing a topological open string theory. In…

Asymptotic commutativity of quantized spaces: the case of $CP^{p, q}$

Fedele Lizzi, A. Pinzul, A. Stern +1

We present a procedure for quantizing complex projective spaces $CP^{p, q}$ , $q \geq 1$ , as well as construct relevant star products on these spaces. The quantization is made…

Charging the Walking U(N) $\times$ U(N) Higgs Theory as a Complex CFT

Oleg Antipin, Jahmall Bersini, Francesco Sannino +2

We apply a semi-classical method to compute the conformal field theory (CFT) data for the U(N)xU(N) non-abelian Higgs theory in four minus epsilon dimensions at its complex fixed p…

The Casimir energy in terms of boundary quantum field theory: the QED case

David Dudal, Pablo Pais, Luigi Rosa

We revisit the path integral computation of the Casimir energy between two infinite parallel plates placed in a QED vacuum. We implement perfectly magnetic conductor boundary condi…

A novel approach to non-commutative gauge theory

Vladislav G. Kupriyanov, Patrizia Vitale

We propose a field theoretical model defined on non-commutative space-time with non-constant non-commutativity parameter $Θ (x)$ , which satisfies two main requirements: it is gauge…

Poisson-Lie T-Duality of WZW Model via Current Algebra Deformation

Francesco Bascone, Franco Pezzella, Patrizia Vitale

Poisson-Lie T-duality of the Wess-Zumino-Witten (WZW) model having the group manifold of $S U (2)$ as target space is investigated. The whole construction relies on the deformation o…

Charging the Conformal Window

Domenico Orlando, Susanne Reffert, Francesco Sannino

We investigate the properties of near-conformal dynamics in a sector of large charge when approaching the lower boundary of the conformal window from the chirally broken phase. To…

Charging the $O (N)$ model

Oleg Antipin, Jahmall Bersini, Francesco Sannino +2

We determine, for the first time, the scaling dimensions of a family of fixed-charge operators stemming from the critical $O (N)$ model in 4- $ε$ dimensions to the leading and next t…

Towards the QED beta function and renormalons at $1/ N_{f}^{2}$ and $1/ N_{f}^{3}$

Nicola Andrea Dondi, Gerald V. Dunne, Manuel Reichert +1

We determine the $1/ N_{f}^{2}$ and $1/ N_{f}^{3}$ contributions to the QED beta function stemming from the closed set of nested diagrams. At order $1/ N_{f}^{2}$ we discover a new logarithmic br…

How many surface modes does one see on the boundary of a Dirac material?

Maxim Kurkov, Dmitri Vassilevich

We present full expressions for the surface part of polarization tensor of a Dirac fermion confined in a half-space in $3 + 1$ dimensions. We compare this tensor to the polarization…

The Momentum Spaces of $κ$ -Minkowski noncommutative spacetime

Fedele Lizzi, Flavio Mercati, Mattia Manfredonia

A useful concept in the development of physical models on the $κ$ -Minkowski noncommutative spacetime is that of a curved momentum space. This structure is not unique: several inequ…
