Quantum Frontiers Distinguished Lecture: Crazy behaviour of light inside solids
David Snoke, University of Pittsburgh
Much of our intuition about light comes from our experience that light has very weak interaction with other light—a beam of light easily passes through another beam of light, so that the Star Wars scenes of “light sabers” bouncing off each other are just imaginary. But in solids, the properties of light can be changed dramatically, especially in solids that we design for new effects.
