Escape dynamics in an anisotropically driven Brownian magneto-system

Abstract Thermally activated escape of a Brownian particle over potential barrier is well understood within Kramers theory. When subjected to an external magnetic field, the Lorentz force slows down dynamics via rescaling diffusion coefficient without affecting exponential dependence on height. Here, we study charged from two-dimensional truncated harmonic under influence due field. The driven anisotropically by subjecting it noises with different strengths along spatial directions. We show that time can largely be tuned anisotropic driving. While process becomes two noises, symmetry restored in limit large fields. This attributed Lorentz-force–induced coupling between degrees freedom which makes difference irrelevant at high theoretical predictions are verified simulations. In principle, our tested experiments gyrator presence
