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…
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…
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(…
Entanglement Negativity on Random Spin Networks
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…
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…
Group Field Theory and Holographic Tensor Networks: Dynamical Corrections to the Ryu-Takayanagi formula
Goffredo Chirco, Alex Goeßmann, Daniele Oriti +1
We introduce group field theory networks as a generalization of spin networks and of (symmetric) random tensor networks and provide a statistical computation of the Rényi entropy f…
Ryu-Takayanagi Formula for Symmetric Random Tensor Networks
Goffredo Chirco, Daniele Oriti, Mingyi Zhang
We consider the special case of Random Tensor Networks (RTN) endowed with gauge symmetry constraints on each tensor. We compute the Rènyi entropy for such states and recover the Ry…
Higher Curvature Gravity and the Holographic fluid dual to flat spacetime
Goffredo Chirco, Christopher Eling, Stefano Liberati
Recent works have demonstrated that one can construct a (d+2) dimensional solution of the vacuum Einstein equations that is dual to a (d+1) dimensional fluid satisfying the incompr…
The universal viscosity to entropy density ratio from entanglement
Goffredo Chirco, Christopher Eling, Stefano Liberati
We present evidence that the universal Kovtun-Son-Starinets shear viscosity to entropy density ratio of 1/4πcan be associated with a Rindler causal horizon in flat spacetime. Since…
