Group field theory on quantum groups
Florian Girelli, Matteo Laudonio
We introduce the framework of Hopf algebra field theory (HAFT) which generalizes the notion of group field theory to the quantum group (Hopf algebra) case. We focus in particular o…
Group field theory on 2-groups
Florian Girelli, Matteo Laudonio, Adrian Tanasa +1
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 manif…
Polyhedron phase space using 2-groups: kappa-Poincare as a Poisson 2-group
Florian Girelli, Matteo Laudonio, Panagiotis Tsimiklis
We construct a phase space for a three dimensional cellular complex with decorations on edges and faces using crossed modules (strict 2-groups) equipped with a (non-trivial) Poisso…
Combinatorial aspects of the Sachdev-Ye-Kitaev model
Matteo Laudonio, Romain Pascalie, Adrian Tanasa
The Sachdev-Ye-Kitaev (SYK) model is a model of interacting fermions whose large N limit is dominated by melonic graphs. In this review we first present a diagrammatic proof of…
Non-Gaussian disorder average in the Sachdev-Ye-Kitaev model
T. Krajewski, M. Laudonio, R. Pascalie +1
We study the effect of non-Gaussian average over the random couplings in a complex version of the celebrated Sachdev-Ye-Kitaev (SYK) model. Using a Polchinski-like equation and ran…
