Renormalization group analysis of a continuous model with self-organized criticality: Effects of randomly moving environment
N. V. Antonov, P. I. Kakin, N. M. Lebedev +1
We study a strongly anisotropic self-organized critical system coupled to an isotropic random fluid environment. The former is described by a continuous (coarse-grained) model due…

Random Walk on a Random Surface: Implications of Non-perturbative Concepts and Dynamical Emergence of Galilean Symmetry
N. V. Antonov, N. M. Gulitskiy, P. I. Kakin +1
We study a model of random walk on a fluctuating rough surface using the field-theoretic renormalization group (RG). The surface is modelled by the well-known Kardar--Parisi--Zhang…
