I'm giving a talk on optically controlled active media today at Frontiers in Optics. The talk number is FTh3D.7 and it's in Highland E.
The talk is about our work concerning the optical forces on colloidal particles in 3D, space and time dependent speckle. I'm pushing it as a model system for testing ideas from nonequilibrium thermodynamics, but I think that our method of treating the field-particle coupling is equally interesting.
Come check it out.
