Finite-Time Transition to Intermittency for a Stochastic Heat Equation Driven by the Square of a Gaussian Field

Philippe Mounaix

In this paper, we study the spatial behavior of the solution $ψ (x, t)$ to the stochastic heat equation $\partial_{t} ψ (x, t) - \frac{1}{2} \partial_{x^{2}}^{2} ψ (x, t) = g S (x, t)^{2} ψ (x, t)$ , w…

Testing the Instanton Approach to the Large Amplification Limit of a Diffraction-Amplification Problem

Philippe Mounaix

The validity of the instanton analysis approach is tested numerically in the case of the diffraction-amplification problem $\partial_zψ-\frac{i}{2m}\partial^2_{x^2} ψ=g\vert S\vert…
