Rapid electron trapping studied by pump-probe photoconductivity: kinetic analysis
Ilya A. Shkrob, Leonid Ryzhik
The use of ultrafast pump-probe conductivity (PPC) for studies of photoelectron dynamics in nonpolar molecular liquids has been based upon the perturbation of geminate recombinatio…
Statistical stability in time reversal
George Papanicolaou, Leonid Ryzhik, Knut Solna
When a signal is emitted from a source, recorded by an array of transducers, time reversed and re-emitted into the medium, it will refocus approximately on the source location. We…
Self-averaging in time reversal for the parabolic wave equation
Guillaume Bal, George Papanicolaou, Leonid Ryzhik
We analyze the self-averaging properties of time-reversed solutions of the paraxial wave equation with random coefficients, which we take to be Markovian in the direction of propag…
Time Reversal for Waves in Random Media
Guillaume Bal, Leonid Ryzhik
In time reversal acoustics experiments, a signal is emitted from a localized source, recorded at an array of receivers-transducers, time reversed, and finally re-emitted into the m…
Time Reversal for Classical Waves in Random Media
Guillaume Bal, Leonid Ryzhik
We propose a mathematical theory for the refocusing properties observed in time-reversal experiments, where classical waves propagate through a medium, are recorded in time, then t…
Quenching of flames by fluid advection
Peter Constantin, Alexander Kiselev, Leonid Ryzhik
We consider a simple scalar reaction-advection-diffusion equation with ignition-type nonlinearity and discuss the following question: What kinds of velocity profiles are capable of…
