From path integral quantization to stochastic quantization: a pedestrian's journey
Dario Benedetti, Ilya Chevyrev, Razvan Gurau
We give two novel proofs that the path integral and stochastic quantizations of generic scalar Euclidean quantum field theories are equivalent. Our proofs rely on Taylor interpolat…

Addendum: Long-range multi-scalar models at three loops
Dario Benedetti, Razvan Gurau, Sabine Harribey
We correct the computation of one Feynman diagram in the three-loop beta functions for the long-range quartic multi-scalar model, originally presented in (2020 J. Phys. A: Math. Th…

Dynamic critical exponent in quantum long-range models
Dario Benedetti, Razvan Gurau, Davide Lettera
Quantum long-range models at zero temperature can be described by fractional Lifshitz field theories, that is, anisotropic models whose actions are short-range in time and long-ran…
