How can the Fokker-Planck equation be used to solve problems in physics and chemistry?
The Fokker-Planck equation is a powerful tool for solving problems in physics and chemistry. It describes the evolution of probability density associated with stochastic differential equations. In higher dimensions, solving this equation using conventional methods becomes computationally prohibitive. However, a fast and scalable method has been introduced that approximates the solution using shape-morphing Gaussians with time-dependent means and covariances. This method, known as the method of reduced-order nonlinear solutions (RONS), ensures that the approximate solution stays close to the true solution of the equation for all times. The proposed method approximates both the transient dynamics and the equilibrium density. It can be viewed as an evolution on a finite-dimensional statistical manifold and has been shown to coincide with the Fisher information matrix. This method is interpretable, requires no training, and automatically satisfies all properties of a probability density . The Fokker-Planck equation also has applications in quantum physics, where it can be transformed into an equation of the Lindblad form. This transformation preserves the trace and positivity of the density operator and provides explicit expressions for the quantum equivalence of probability current and detailed balance . Additionally, the Fokker-Planck equation is used in non-equilibrium thermodynamics to describe systems with non-equilibrium physics behavior. It is connected to entropy generation and entropy production methods, allowing for a deeper understanding of energy generation and energy production in these systems . Finally, the Fokker-Planck equation is used to propagate uncertainty in dynamical systems driven by stochastic processes. A novel numerical method based on physics-based mixture models has been developed to solve the Fokker-Planck equation, capturing the tail behavior of the solution PDF and satisfying the necessary conditions of a proper PDF with unbounded support .
