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 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.

Magnetic quivers and line defects — On a duality between 3d N $$ \mathcal{N} $$ = 4 unitary and orthosymplectic quivers

Journal of High Energy Physics, 2022
Supersymmetric Sp(k) quantum chromodynamics with 8 supercharges in space-time dimensions 3 to 6 can be realised by two different Type II brane configurations in the presence of orientifolds.

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.

EPRL/FK group field theory [PDF]

EPL (Europhysics Letters), 2010
The purpose of this short note is to clarify the Group Field Theory vertex and propagators corresponding to the EPRL/FK spin foam models and to detail the subtraction of leading divergences of the model.

(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.

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.

Bosonic colored group field theory [PDF]

The European Physical Journal C, 2010
Bosonic colored group field theory is considered. Focusing first on dimension four, namely the colored Ooguri group field model, the main properties of Feynman graphs are studied. This leads to a theorem on optimal perturbative bounds of Feynman amplitudes in the "ultraspin" (large spin) limit. The results are generalized in any dimension.
