Strict deformation quantization and local spin interactions
Nicolò Drago, Christiaan J. F. van de Ven
We define a strict deformation quantization which is compatible with any Hamiltonian with local spin interaction (e.g. the Heisenberg Hamiltonian) for a spin chain. This is a gener…

An algebraic QFT approach to the Wetterich equation on Lorentzian manifolds
Edoardo D'Angelo, Nicolò Drago, Nicola Pinamonti +1
We discuss the scaling of the effective action for the interacting scalar quantum field theory on generic spacetimes with Lorentzian signature and in a generic state (including vac…
