Title: Vortices, Skyrmions, Möbius Strips: From Nanooptics to Ocean Waves
Abstract:
Prof. Konstantin Bliokh will present recent theoretical and experimental results on: (i) subwavelength high-intensity vortices around ‘holes’ or ‘islands’ in 2D wave systems: from polaritons to ocean waves, (ii) generation of the Bessel-type vortices, displacement-field skyrmions, and polarization Möbius strips in sound and water waves, and (iii) manipulation of floating particles using topologically structured water waves.
Professor Konstantin Bliokh received his PhD degree in physics from Kharkov National University (Ukraine) in 2001. After that, he worked at the Institute of Radio Astronomy (Ukraine), Bar-Ilan University (Israel), Technion–Israel Institute of Technology (Israel), the National University of Ireland (Ireland), the Australian National University (Australia), and RIKEN (Japan). He is currently an Ikerbasque Professor at the Donostia International Physics Center (Spain).
Prof. Bliokh's research areas include: complex wave systems, geometric phases, spin-orbit interactions, wave momentum and angular momentum, wave vortices, wave-matter interactions. He has co-authored more than 130 scientific papers, reviews, and book chapters.
The research of the Optics and Photonics group covers a range of topics of modern optics and photonics, encompassing various aspects of light-matter interaction, optical coherence and polarization, development of methods to manipulate light with nano- and micro-structures, design and construction of novel light sources, optical metamaterials and optical imaging.
