Abstract :

The rays of light carry energy as well as linear and angular momentum. The latter properties are exploited in solar sails, optical tweezers, and micro/nano opto-mechanical motors and actuators. A fundamental characteristic of photons, their momentum in the presence of material media, has been the subject of debate and controversy for more than a century. The so- called Abraham-Minkowski controversy involves theoretical arguments in conjunction with experimental tests to determine whether the vacuum photon momentum must be divided or multiplied by the refractive index of the host medium. Also, momentum conservation is intimately tied to the force law that specifies the rate of exchange of electromagnetic and mechanical momentum between light and matter. In this presentation the author will discuss the foundational postulates of the Maxwell- Lorentz theory of electrodynamics that clarify the prevailing ambiguities and resolve the reigning controversies.
