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…

Critical and multicritical Lee-Yang fixed points in the local potential approximation
Dario Benedetti, Fanny Eustachon, Omar Zanusso
The multicritical generalizations of the Lee-Yang universality class arise as renormalization-group fixed points of scalar field theories with complex interaction, $n\i…
