UV/IR mixing as an artifact of non-covariant quantisation
Kilian Hersent, Flavio Mercati
We study the path integral quantisation of a scalar field on a generic noncommutative deformation of Minkowski space, built as a quantum homogeneous space of a deformed Poincaré gr…

Thermal time of noncommutative Minkowski spacetime
Kilian Hersent
In this paper, we study the thermal time hypothesis of arXiv:gr-qc/9406019 in the context of noncommutative deformations of Minkowski. We show that a natural modular group arises f…

Field Theories on Quantum Space-Times: Towards the Phenomenology of Quantum Gravity
Kilian Hersent
Noncommutative geometry is a mathematical framework that expresses the structure of space-time in terms of operator algebras. By using the tools of quantum mechanics to describe th…
