QJMAM/IMA Summer School:

Asymptotic Methods for PDEs & Modelling of Waves

The Summer school is aimed at postgraduate students and postdoctoral researchers working on the mathematical modelling of waves. The focus of the school will be on Asymptotic Methods for Partial Differential Equations and will combine analytical techniques with numerical modelling. This course will enable, both new and more experienced, researchers to gain theoretical knowledge and practical skills in the modelling of wave propagation in multi-scale structured media. Combined with asymptotic techniques, and in particular the method of meso-scale asymptotic approximations, the solutions and numerical simulations are elegant and effective. The conceptual and theoretical ideas that underpin the method will be explained and accompanied by illuminating analytical and numerical implementations demonstrated during lectures and practical sessions. MATLAB and COMSOL Multi-Physics will be used as the programming environment in most of the numerical demonstrations.

The lectures and numerical demonstrations will be delivered by Prof Alexander Movchan, Prof Natasha Movchan, Dr Daniel Colquitt, Dr Stewart Haslinger, Dr Ozgur Selsil, and Dr Sara Frecentese and will include both rigorous analysis and illustrative numerical simulations, with links to original research results and recent publications.

All sessions will run online, via ZOOM, the lectures and numerical demonstrations will take place on weekdays during 19 July 2021 – 6 August 2021 (there will be no sessions on weekends). Each day will consist of a two-hour instructional session per day, with additional tutorials run as discussion sessions.

Summary videos for the sessions will be provided to all participants. The registration is required to provide access for all participants to the Zoom sessions and online video supplementary material. All sessions are free, there is no charge.

1st metaMAT anniversary meeting, Tuesday 27 July 2021, 14:00 (London Time)

Speaker 1: Martin Wegener (Karlsruhe Institute of Technology)

Title: Roton Metamaterials

Abstract: Based on the pioneering work of Lev Landau and Richard Feynman, rotons were observed in inelastic neutron scattering experiments on superfluid helium in 1961. For the roton dispersion relation, energy and momentum of the acoustical wave are proportional to each other for small momenta. For larger momenta, a (roton) minimum of energy versus momentum occurs. Rotons have also been investigated in other correlated quantum systems at low temperatures, such as quasi two-dimensional thin films of 3He, quantum Hall effect stripes in semiconductors, and Bose-Einstein condensates of atoms. In this talk, we present the physics and design of metamaterials showing roton dispersion relations under ambient conditions.

Biography: After completing his Diplom and PhD in physics at Johann Wolfgang Goethe-Universität Frankfurt (Germany) in 1986 and 1987, respectively, he spent two years as a postdoc at AT&T Bell Laboratories in Holmdel (U.S.A.). From 1990-1995 he was professor (C3) at Universität Dortmund (Germany), since 1995 he is professor (C4, later W3) at Institute of Applied Physics of Karlsruhe Institute of Technology (KIT). Since 2001 he has a joint appointment as department head at Institute of Nanotechnology (INT) of KIT, since 2016 he is one of three directors at INT. From 2001-2014 he was the coordinator of the DFG- Center for Functional Nanostructures (CFN) at KIT. Since 2018 he is spokesperson of the Cluster of Excellence 3D Matter Made to Order. His research interests comprise ultrafast optics, (extreme) nonlinear optics, optical laser lithography, photonic crystals, optical, mechanical, electronic, and thermodynamic metamaterials, as well as transformation physics. This research has led to various awards and honors, among which are the Alfried Krupp von Bohlen und Halbach Research Award 1993, the Baden- Württemberg Teaching Award 1998, the DFG Gottfried Wilhelm Leibniz Award 2000, the European Union René Descartes Prize 2005, the Baden-Württemberg Research Award 2005, the Carl Zeiss Research Award 2006, the Hector Research Award 2008, the SPIE Prism Award 2014 for the start-up company Nanoscribe GmbH, the Stifterverband Science Award – Erwin-Schrödinger Prize 2016, and the Technology Transfer Prize of the German Physical Society (DPG) 2018. In 2014, 2015, 2016, 2017, 2018, and 2020 Clarivate Analytics listed him as “Highly Cited Researcher” (top 1%). He is Member of Leopoldina, the German Academy of Sciences (since 2006), Member of acatech, the National Academy of Science and Engineering (since 2019), Member of the Hector Fellow Academy (since 2013, presently also President), Fellow of the Max Plack School of Photonics (since 2019), Fellow of the Optical Society of America (since 2008), and Honorary Professor at Huazhong University of Science & Technology, Wuhan, China (since 2014).

& Seminar 52, Tuesday 27 July 2021, 17:00 (London Time)

Speaker 2: Tadashi Tokieda (Department of Mathematics, Stanford University, California, USA)

Title: Toy models

Abstract: Would you like to come see some toys?

‘Toys’ here have a special sense: objects of daily life which you can find or make in minutes, yet which, if played with imaginatively, reveal surprises that keep scientists puzzling for a while.

We will see table-top demos of a diversity of such toys, in which we will notice new effects, from which we will try to extract some fresh, simple models. A common theme that emerges is singularity. (This was given as a public lecture at the International Congress of Mathematicians in Rio de Janeiro, 2018.)

Biography: Tadashi Tokieda grew up as a painter in Japan, became a classical philologist (not to be confused with philosopher) in France, before switching to mathematics and later physics.  Having lived in 8 countries, he is now a professor of mathematics at Stanford; previously he worked for many years at Cambridge.  He is also active in outreach in the developing world, especially via African Institute for Mathematical Sciences.
