Gauge-covariant Hadamard descent in Yang-Mills theory
Lucio Vacchiano, Goffredo Chirco, Saverio Pascazio +1
We study the dimensional reduction of non-Abelian Yang-Mills theory from five to four dimensions. In this framework, Hadamard descent is formulated as a restriction to gauge-equiva…
Dimensional reduction of AdS3 Chern-Simons gravity: Schwarzian and affine boundary theories
Goffredo Chirco, Lucio Vacchiano, Patrizia Vitale
We study a symmetry-reduced sector of gravity formulated as an Chern--Simons theory on a three-dimensional manifold with toroidal boundary. The reduction is imple…
Hamiltonian formulation of a gravity model from (A)dS Yang-Mills theory
Goffredo Chirco, Alfonso Lamberti, Patrizia Vitale
We study the Hamiltonian formulation of a gravity model obtained from a Yang--Mills theory for a one-parameter family of (A)dS Lie algebras parametrized by , when the family of…
Bias in Local Spin Measurements from Deformed Symmetries
Michele Arzano, Goffredo Chirco, Jerzy Kowalski-Glikman
We study local spin measurements on bipartite singlet states when rotational symmetry is described by a quantum group rather than an ordinary Lie group. Although the fundamental sp…
Operator Entanglement from Non-Commutative Symmetries
Michele Arzano, Goffredo Chirco
We argue that Hopf-algebra deformations of symmetries -- as encountered in non-commutative models of quantum spacetime -- carry an intrinsic content of th…
Gravity model from (A)dS Yang-Mills theory
Goffredo Chirco, Alfonso Lamberti, Lucio Vacchiano +1
We investigate the relationship between a one-parameter family of (anti-)de Sitter Yang-Mills models and a model of Einstein-Palatini gravity with matter, realized through Inönu-Wi…

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…
Stabilizer entropy of quantum tetrahedra
Simone Cepollaro, Goffredo Chirco, Gianluca Cuffaro +2
How complex is the structure of quantum geometry? In several approaches, the spacetime atoms are obtained by the SU(2) intertwiner called quantum tetrahedron. The complexity of thi…
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(…

Goffredo Chirco, Simone Cepollaro, Gianluca Cuffaro +1
We investigate multipartite entanglement for quantum states of 3d space geometry, described via generalised random spin networks with fixed areas, in the context of background inde…
Dually affine Information Geometry modeled on a Banach space
Goffredo Chirco, Giovanni Pistone
In this chapter, we study Information Geometry from a particular non-parametric or functional point of view. The basic model is a probabilities subset usually specified by regulari…
Bulk area law for boundary entanglement in spin network states: entropy corrections and horizon-like regions from volume correlations
Goffredo Chirco, Eugenia Colafranceschi, Daniele Oriti
For quantum gravity states associated to open spin network graphs, we study how the entanglement entropy of the boundary degrees of freedom (spins on open edges) is affected by the…
Holographic maps from quantum gravity states as tensor networks
Eugenia Colafranceschi, Goffredo Chirco, Daniele Oriti
We define bulk/boundary maps corresponding to quantum gravity states in the tensorial group field theory formalism, for quantum geometric models sharing the same type of quantum st…
