Different Ways of Seeing Light
Dr Almut Beige, University of Leeds
The physics of light has an exciting history with a wide range of theoretical controversies and experimental surprises. Depending on the circumstances, we sometimes associate light with rays or with waves. In other situations we study the dynamics of electric and magnetic fields or introduce photon states and scattering operators. In this talk, we show that ambiguity arises when we try to derive quantum from classical electrodynamics. We employ different approaches to the quantised electromagnetic field and investigate the differences in their physical predictions.
