Holographic Entanglement in Group Field Theory [PDF]
Universe, 2019 This work is meant as a review summary of a series of recent results concerning the derivation of a holographic entanglement entropy formula for generic open spin network states in the group field theory (GFT) approach to quantum gravity. The statistical

Group Field Theory: An Overview [PDF]
International Journal of Theoretical Physics, 2005 We give a brief overview of the properties of a higher dimensional generalization of matrix model which arises naturally in the context of a background independent approach to quantum gravity, the so called group field theory. We show that this theory leads to a natural proposal for the physical scalar product of quantum gravity.

Group Field Theory Condensate Cosmology: An Appetizer [PDF]
Universe, 2019 This contribution is an appetizer to the relatively young and fast-evolving approach to quantum cosmology based on group field theory condensate states. We summarize the main assumptions and pillars of this approach which has revealed new perspectives on

Precision boson-jet azimuthal decorrelation at hadron colliders
Journal of High Energy Physics, 2023 The azimuthal angular decorrelation of a vector boson and jet is sensitive to QCD radiation, and can be used to probe the quark-gluon plasma in heavy-ion collisions.

Confinement in the tricritical Ising model
Physics Letters B, 2022 We study the leading and sub-leading magnetic perturbations of the thermal E7 integrable deformation of the tricritical Ising model. In the low-temperature phase, these magnetic perturbations lead to the confinement of the kinks of the model.

Group field theory on 2-groups
Physical Review D, 2023 Group field theories are quantum field theories built on groups. They can be seen as a tool to generate topological state-sums or quantum gravity models. For four dimensional manifolds, different arguments have pointed towards 2-groups (such as crossed modules) as the relevant symmetry structure to probe four dimensional topological features.

(No) phase transition in tensorial group field theory
Physics Letters B, 2021 Continuum spacetime is expected to emerge via phase transition in discrete approaches to quantum gravity. A promising example is tensorial group field theory but its phase diagram remains an open issue.

Quantum Fluctuations in the Effective Relational GFT Cosmology
Frontiers in Astronomy and Space Sciences, 2021 We analyze the size and evolution of quantum fluctuations of cosmologically relevant geometric observables, in the context of the effective relational cosmological dynamics of GFT models of quantum gravity.
