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\…

Physical Running in Conformal Gravity and Higher Derivative Scalars
Diego Buccio, Luca Parente, Omar Zanusso
We compute the physical running of a general higher derivative scalar coupled to a nondynamical metric and of higher derivative Weyl invariant gravity with a dynamical metric in fo…
