Colored discrete spaces: higher dimensional combinatorial maps and quantum gravity
Luca Lionni
In any dimension , the Euclidean Einstein-Hilbert action, which describes gravity in the absence of matter, can be discretized over random discrete spaces obtained by gluing fam…

Multi-critical behaviour of 4-dimensional tensor models up to order 6
Luca Lionni, Johannes Thürigen
Tensor models generalize the matrix-model approach to 2-dimensional quantum gravity to higher dimensions. Some models allowing a expansion have been explored, most of them ge…

Diagrammatics of a colored SYK model and of an SYK-like tensor model, leading and next-to-leading orders
Valentin Bonzom, Luca Lionni, Adrian Tanasa
The Sachdev-Ye-Kitaev (SYK) model is a model of interacting fermions. Gross and Rosenhaus have proposed a generalization of the SYK model which involves fermions with different…
