Two-Loop Turbulent Helical Magnetohydrodynamics: Large-Scale Dynamo and Energy Spectrum
Michal HnatiÄ, Tomáš LuÄivjanský, Lukáš MižiÅ¡in +2
We present a two-loop field-theoretic analysis of incompressible helical magnetohydrodynamics (MHD) in fully developed stationary turbulence. A key feature of helical MHD is the ap…

Field-theoretic Analysis of Dynamic Isotropic Percolation: Three-loop Approximation
Michal HnatiÄ, Matej Kecer, Mikhail V. Kompaniets +3
The general epidemic process is a paradigmatic model in non-equilibrium statistical physics displaying a continuous phase transition between active and absorbing states.The dynamic…

Approximate calculation of functional integrals arising from the operator approach
Edik Ayryan, Ján BuÅ¡a, Michal HnatiÄ +2
We apply the operator approach to a stochastic system belonging to a class of death-birth processes, which we introduce utilizing the master equation approach. By employing Doi- Pe…
