Salam Distinguished Lectures 2017
ICTP's Salam Distinguished Lecture Series is an annual presentation of talks by renowned, active scientists. The aim is to showcase important research developments as well as provide a visionary forward view. The lecture series is supported by the Kuwait Programme at ICTP.
The series is a yearly appointment, lectures given in 2012-2016 are available at: http://www.ictp.it/about-ictp/salam-lecture-series.aspx
Salam Distinguished Lectures 2017: "Superoscillations: unexpected fine detail and extreme values in mathematics and quantum and wave physics"
Sir Michael Berry
Abstract: Functions can exhibit structures much smaller that their finest Fourier components, in ways that are not only mathematically interesting but have implications in several areas of science, ranging from optics and quantum physics to signal processing. The lectures will include some or all of the following topics: Basics, shifted fourier transforms, phase–space interpretations (Wigner and Husimi functions), optical singularities (‘vorticulture’), supershifts in weak measurements, superoscillation statistics (in optical fields, backflow, Klein-Gordon and Dirac equations), quantum supershifts, sensitivity to noise, Goos-Hänchen and related shifts, proagation of superoscillations, radar superdirectivity and optical superresolution.
Sir Michael Berry
Melville Wills Physics Professor of Physics (Emeritus) at the University of Bristol, UK.
After graduating from Exeter and St Andrews, Michael Berry entered Bristol University, where he has been for more than twice as long he has not. He is a physicist, focusing on the physics of the mathematics…of the physics. Applications include the geometry of singularities (caustics on large scales, vortices on fine scales) in optics and other waves, connections between classical and quantum physics, and the physical asymptotics of divergent series. He delights in finding the arcane in the mundane – abstract and subtle concepts in familiar or dramatic phenomena: Singularities of smooth gradient maps in rainbows and tsunamis; The Laplace operator in oriental magic mirrors; Elliptic integrals in the polarization pattern of the clear blue sky; Geometry of twists and turns in quantum indistinguishability; Matrix degeneracies in overhead-projector transparencies; Gauss sums in the light beyond a humble diffraction grating.
