Momentum space CFT correlators of non-conserved spinning operators

Raffaele Marotta, Kostas Skenderis, Mritunjay Verma

We analyse the 3-point CFT correlators involving non-conserved spinning operators in momentum space. We derive a general expression for the conformal Ward identities defining the 3…

Quantum particles in non-commutative space-time: an identity crisis

Michele Arzano, Jerzy Kowalski-Glikman

We argue that the notion of identical particles is no longer well defined in quantum systems governed by non-commutative deformations of space-time symmetries. Such models are char…

-Galilean and -Carrollian noncommutative spaces of worldlines

Angel Ballesteros, Giulia Gubitosi, Ivan Gutierrez-Sagredo +1

The noncommutative spacetimes associated to the -Poincaré relativistic symmetries and their "non-relativistic" (Galilei) and "ultra-relativistic" (Carroll) limits are indistingu…

No-signaling-in-time as a condition for macrorealism: the case of neutrino oscillations

Massimo Blasone, Fabrizio Illuminati, Luciano Petruzziello +2

We consider two necessary and sufficient conditions for macrorealism recently appeared in the literature, known as no-signaling-in-time and arrow-of-time conditions, respectively,…

On the classical Integrability of Poisson-Lie T-dual WZW models

Francesco Bascone, Franco Pezzella, Patrizia Vitale

We consider the integrability of a two-parameter deformation of the Wess-Zumino-Witten model, previously introduced in relation with Poisson-Lie T-duality. The resulting family of…

Poisson gauge models and Seiberg-Witten map

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

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 t…

The Casimir effect in chiral media using path integral techniques

Fabrizio Canfora, David Dudal, Thomas Oosthuyse +2

We employ path integral methods to calculate the Casimir energy and force densities in a chiral extension of QED. Manifestly gauge invariant perfect electromagnetic boundary condit…

The -angle and axion physics of two-color QCD at fixed baryon charge. Part I

Jahmall Bersini, Alessandra D'Alise, Francesco Sannino +1

We analyze the impact of the -angle and axion dynamics for two-color (in fact any ) QCD at nonzero baryon charge and as a function of the number of matter fields on the…

From Celestial Correlators to AdS, and back

Lorenzo Iacobacci, Charlotte Sleight, Massimo Taronna

We present a general relation between celestial correlation functions in -dimensions and Witten diagrams in -dimensional Euclidean anti-de Sitter (EAdS) space,…

Charging the conformal window at nonzero angle

Jahmall Bersini, Alessandra D'Alise, Francesco Sannino +1

We determine the impact of the -angle and axion physics on the near conformal dynamics of the large-charge baryon sector of gauge theories with fermions in the fun…

On the robustness of solitons crystals in the Skyrme model

Gonzalo Barriga, Fabrizio Canfora, Marcela Lagos +2

In this work we analize how the inclusion of extra mesonic degrees of freedom affect the finite density solitons crystals of the Skyrme model. In particular, the first analytic exa…

Krylov complexity and orthogonal polynomials

Wolfgang Mück, Yi Yang

Krylov complexity measures operator growth with respect to a basis, which is adapted to the Heisenberg time evolution. The construction of that basis relies on the Lanczos algorith…

Localization and observers in -Minkowski spacetime

Fedele Lizzi, Luca Scala, Patrizia Vitale

We consider the -Minkowski spacetime, a model with linear noncommutativity involving the time and the azimuthal angle. We study its quantum symmetries, the -Poinc…

A group theoretic description of the -Poincaré Hopf algebra

Michele Arzano, Jerzy Kowalski-Glikman

It is well known in the literature that the momentum space associated to the -Poincaré algebra is described by the Lie group . In this letter we show th…

Soft-Theorems for Scalar Particles: The Dilatons Story

Raffaele Marotta

We summarize recent results regarding single and double soft theorems of two different particles named dilatons, the Nambu-Goldstone boson of the spontaneously broken conformal fie…

The analytic structure of the fixed charge expansion

Oleg Antipin, Jahmall Bersini, Francesco Sannino +1

We investigate the analytic properties of the fixed charge expansion for a number of conformal field theories in different space-time dimensions. The models investigated here are $…

On the L structure of Poisson gauge theory

O. Abla, V. G. Kupriyanov, M. Kurkov

The Poisson gauge theory is a semi-classical limit of full non-commutative gauge theory. In this work we construct an L algebra which governs both the action of gau…
