A Gauge-Inspired Coupled Fokker--Planck System for Multistate Stochastic Dynamics: Formalism and 1-D Numerical Implementation

Francesco Pio De Cosmo, Gianluca Di Natale, Leandro Cieri

Extending the Fokker--Planck equation to a coupled system of equations through non-Abelian symmetry groups offers a powerful theoretical framework for coupled multi-state stochasti…
