Complex Patterns in Reaction-Diffusion Systems: A Tale of Two Front Instabilities

, 1994
Two front instabilities in a reaction-diffusion system are shown to lead to the formation of complex patterns. The first is an instability to transverse modulations that drives the formation of labyrinthine patterns.

Measuring the quantum efficiency of single radiating dipoles using a scanning mirror

, 2005
Using scanning probe techniques, we show the controlled manipulation of the radiation from single dipoles. In one experiment we study the modification of the fluorescence lifetime of a single molecular dipole in front of a movable silver mirror. A second

Analytical treatment of 2D steady flames anchored in high-velocity streams

, 2009
The problem of burning of high-velocity gas streams in channels is revisited. Previous treatments of this issue are found to be incomplete. It is shown that despite relative smallness of the transversal gas velocity, it plays crucial role in determining ...
