HKIAS* Distinguished Lecture Series: Materials that move faster than light
Einstein’s theory of relativity sets a limit to the speed of an object: no faster than light. But there is more than one sort of motion: here we are concerned with virtual motion where a material changes its properties in time but nothing materials moves: think of a wave on the ocean which moves but without transporting any water.
When things move that fast they strongly influence the way light moves through them. They break time reversal symmetry, they can capture light and amplify it, they can spontaneously emit radiation. The speaker will talk about the theory behind these process and review the current state of experiments that are realising this version.
