Constraint effective action and critical correlation functions at fixed magnetization
The authors derive exact flow equations for the constraint effective action in the Ising class using FRG, solve them numerically at second-order derivative expansion for 2D and 3D systems, extract universal rate functions and momentum-dependent correlations, and benchmark against Monte Carlo.

Exponents and front fluctuations in the quenched Kardar-Parisi-Zhang universality class of one- and two- dimensional interfaces
Numerical simulations of quenched KPZ interfaces in 1D and 2D confirm the directed percolation depinning exponents and show non-Gaussian front fluctuation PDFs that differ from time-dependent KPZ noise.
