Query: Stochastic Renormalization Group and Gradient Flow in Scalar Field
  Theory   Recently, the connections between gradient flow and renormalization group
have been explored analytically and numerically. Gradient flow (when modified
by a field rescaling) can be characterized as a continuous blocking
transformation. In this work, we draw a connection between gradient flow and
functional renormalization group by describing how FRG can be represented by a
stochastic process, and how the stochastic observables relate to gradient flow
observables. The relation implies correlator scaling formulae that can be
applied numerically in lattice simulations. We present preliminary results on
anomalous dimensions obtained from such measurements in the context of
3-dimensional lattice $\phi^4$ theory.
