NASC Colloquium: Shaping Waves
Andrew Forbes, Distinguished Professor, School of Physics, University of the Witwatersrand, South Africa, will speak on Interference, the quintessential property of wave optics, as a venerable topic that spans centuries of study, influencing how we understand both the classical and quantum worlds. In fact, little has changed since the seminal work of Young with his double slit experiment, performed even to this day in much the same way as he did it. We routinely use such concepts to shape light, but can they be extended to shaping waves in general? In this talk he will revisit the central paradigms in interference as they pertain to shaping light, and show how to extend the ideas to non-optical wave control and outline through simple demonstrations that interference fringes may be observed in places one may not think to look, and that both classical and quantum waves can be shaped to desired profiles. In the process he will provide a complete resource for DIY experiments that incorporates modern digital tools with 3D printed components to bring the classical and quantum interference concepts alive in the laboratory.
