Les Houches lectures on Spinfoam Path Integrals
Oleksandra Hrytseniak, Etera R. Livine, Valentine Maris
In these lecture notes for the Les Houches School on Loop Quantum Gravity 2025, which took place in September 2025, we give a pedagogical review of the basics of the spinfoam frame…
Quantum causality in kappa Minkoswki
Valentine Maris
Recent results on causality in noncommutative space-time are reviewed. We study, in particular, quantum causal structures in 1+1 dimensional kappa Minkowski space-time. This later…
Star-products for Lie-algebraic noncommutative Minkowski space-times
Valentine Maris, Filip Požar, Jean-Christophe Wallet
Poisson structures of the Poincaré group can be linked to deformations of the Minkowski space-time, classified some time ago by Zakrewski. Based on this classification, various qua…
Matter coupled to 3d Quantum Gravity: One-loop Unitarity
Etera R. Livine, Valentine Maris
We expect quantum field theories for matter to acquire intricate corrections due to their coupling to quantum fluctuations of the gravitational field. This can be precisely worked…
