Modular theory and affine representations on the Rindler horizon
Michele Arzano, Paolo Palumbo
We develop a group-theoretic interpretation of the Unruh effect based on affine symmetry on a light ray and relate it to modular theory. For a massless scalar field in two spacetim…
olographic aturalness and Pre-Geometric Gravity
Andrea Addazi, Salvatore Capozziello, Giuseppe Meluccio
The cosmological constant (CC, ) problem represents a remarkable discrepancy of about 120 orders of magnitude between the observed dark energy and its natural expectation from q…
The electromagnetic field in Poisson gauge theory: the groupoidal approach
Fabio Di Cosmo, Vladislav G. Kupriyanov, Patrizia Vitale
We consider the problem of defining the field strength of abelian potentials when the spacetime is a Poisson manifold, within the groupoidal approach. The natural definition in ter…
Thermodynamics of magnetized BPS baryonic layers and the effects of the Isospin chemical potential
Sergio Luigi Cacciatori, Fabrizio Canfora, Evangelo Delgado +2
Through the Hamilton-Jacobi equation of classical mechanics, BPS magnetized Baryonic layers (possessing both baryonic charge and magnetic flux) have been constructed in the gauged…
Vacuum configuration of winding superstrings from non-standard semiclassical quantization
Tommaso Canneti, Federico Castellani, Wolfgang Mück
Semiclassical quantization techniques are unreliable, if the magnitude of the quantum fluctuations becomes comparable with a classical background scale. This is the case, for examp…
Visions in Quantum Gravity
Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…
A so(2,2) extension of JT gravity via the Virasoro-Kac-Moody semidirect product
Goffredo Chirco, Lucio Vacchiano, Patrizia Vitale
We consider a bulk plus boundary extension of Jackiw-Teitelboim Gravity (JT) coupled with non-abelian gauge fields. The generalization is performed in the Poisson Sigma Model formu…
Gravity from Pre-geometry
Andrea Addazi, Salvatore Capozziello, Antonino Marciano +1
The gravitational interaction, as described by the Einstein-Cartan theory, is shown to emerge as the by-product of the spontaneous symmetry breaking of a gauge symmetry in a pre-ge…
On the physical and mathematical foundations of quantum physics via functional integrals
Giampiero Esposito, Tepper L. Gill
In order to preserve the leading role of the action principle in formulating all field theories one needs quantum field theory, with the associated BRST symmetry, and Feynman-DeWit…
Hagedorn temperature in holography: world-sheet and effective approaches
Francesco Bigazzi, Tommaso Canneti, Federico Castellani +2
We provide general results on the Hagedorn temperature of planar, strongly coupled confining gauge theories holographically dual to type II superstring models on curved backgrounds…
Jacobi Sigma Models and Twisted Jacobi Structures
Francesco Bascone, Franco Pezzella, Patrizia Vitale
Jacobi sigma models are two-dimensional topological non-linear field theories which are associated with Jacobi structures. The latter can be considered as a generalization of Poiss…
Gravitational back-reaction is magical
ChunJun Cao, Gong Cheng, Alioscia Hamma +3
We study the interplay between magic and entanglement in quantum many-body systems. We show that non-local magic, which is supported by the quantum correlations is lower bounded by…
Hamiltonian analysis in Lie-Poisson gauge theory
Francesco Bascone, Maxim Kurkov
Lie-Poisson gauge formalism provides a semiclassical description of noncommutative gauge theory with Lie algebra type noncommutativity. Using the Dirac approach to constrain…
Multiparticle states in braided lightlike -Minkowski noncommutative QFT
Giuseppe Fabiano, Flavio Mercati
In this study, we construct a 1+1-dimensional, relativistic, free, complex scalar Quantum Field Theory on the noncommutative spacetime known as lightlike -Minkowski. The associa…
Noncommutative spacetimes versus noncommutative spaces of geodesics
Francisco J. Herranz, Angel Ballesteros, Giulia Gubitosi +1
The aim of this contribution is twofold. First, we show that when two (or more) different quantum groups share the same noncommutative spacetime, such an 'ambiguity' can be resolve…
Semiclassical Quantization of the Superstring and Hagedorn Temperature
Francesco Bigazzi, Tommaso Canneti, Wolfgang Mück
In a recent paper [1], the semiclassical quantization of a string, winding once around the compact Euclidean time circle, on a supergravity background dual to the deep infrared reg…
Quantum Hair During Gravitational Collapse
Xavier Calmet, Roberto Casadio, Stephen D. H. Hsu +1
We consider quantum gravitational corrections to the Oppenheimer-Snyder metric describing time-dependent dust ball collapse. The interior metric also describes Friedmann-Lemaitre-R…
Curvature from multipartite entanglement in quantum gravity states
Simone Cepollaro, Goffredo Chirco, Gianluca Cuffaro +1
We investigate the multipartite entanglement of a uniformly curved quantum 3D space region with boundary, realised in terms of spin networks defined on a graph with non trivial SU(…
Lie-Poisson gauge theories and -Minkowski electrodynamics
V. G. Kupriyanov, M. A. Kurkov, P. Vitale
We consider gauge theories on Poisson manifolds emerging as semiclassical approximations of noncommutative spacetime with Lie algebra type noncommutativity. We prove an important i…
Beyond AdS/dCFT: Insertions in Two Wilson Loops
Diego H. Correa, Alberto Faraggi, Wolfgang Mück +2
We consider two-point correlators of local operator insertions in a system of two Wilson-Maldacena loops in supersymmetric Yang-Mills theory on both sides of the AdS/C…
Total momentum and other Noether charges for particles interacting in a quantum spacetime
Giovanni Amelino-Camelia, Giuseppe Fabiano, Domenico Frattulillo
There has been strong interest in the fate of relativistic symmetries in some quantum spacetimes, also because of its possible relevance for high-precision experimental tests of re…
The minimal length: a cut-off in disguise?
Pasquale Bosso, Luciano Petruzziello, Fabian Wagner
The minimal-length paradigm, a possible implication of quantum gravity at low energies, is commonly understood as a phenomenological modification of Heisenberg's uncertainty relati…
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…
