Propagation of nonlinear waves in disordered media

Speaker: Boris Spivak , Univ. of Washington

When: March 10, 2021 (Wed), 02:00PM to 03:00PM (add to my calendar)

This event is part of the Biophysics/Condensed Matter Seminar Series.

We study the propagation of stationary waves in disordered nonlinear media described by the nonlinear Schrödinger equation and show that, for given boundary conditions and a given coherent wave incident on the sample, the number of solutions of the equation increases exponentially with sample size. We also discuss the ballistic case, the sensitivity of the solutions to the change of external parameters, the similarity of this problem to the problem of spin glasses, and time-dependent solutions.
