Multiparticle states in braided lightlike $κ$ -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 $κ$ -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 $κ$ -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 $_{2}$ /dCFT $_{1}$ : 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 $N = 4$ 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…
