Bias in Local Spin Measurements from Deformed Symmetries
Michele Arzano, Goffredo Chirco, Jerzy Kowalski-Glikman
The paper investigates how local spin measurements on entangled singlet states are affected when rotational symmetry is modeled by a quantum group, showing that conventional and br…
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…
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-W…
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…
