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.

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.

Double field theory on group manifolds [PDF]

Journal of High Energy Physics, 2015
A new version of double field theory (DFT) is derived for the exactly solvable background of an in general left-right asymmetric WZW model in the large level limit. This generalizes the original DFT that was derived via expanding closed string field theory on a torus up to cubic order.

Inverse Renormalization Group in Quantum Field Theory [PDF]

Physical Review Letters, 2022
We propose inverse renormalization group transformations within the context of quantum field theory that produce the appropriate critical fixed point structure, give rise to inverse flows in parameter space, and evade the critical slowing down effect in calculations pertinent to criticality.

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.

Overlap singularity and time evolution in integrable quantum field theory

Journal of High Energy Physics, 2018
We study homogeneous quenches in integrable quantum field theory where the initial state contains zero-momentum particles. We demonstrate that the two-particle pair amplitude necessarily has a singularity at the two-particle threshold.
