Abstract:

I will present recent theoretical and experimental results on: (i) subwavelength high-intensity vortices around holes 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.

Konstantin Bliokh received the MSc and PhD degrees in physics from the Kharkov National University (Ukraine) in 1998 and 2001, respectively. After that, he worked as a research scientist at the Institute of Radio Astronomy (Ukraine, 2001–2009). He was a post-doctoral fellow at Bar-Ilan University (Israel, 2003–2005), a visiting research scientist at Technion–Israel Institute of Technology (Israel, 2007), a Linkage International research fellow at the Australian National University (Australia, 2008–2009), a Marie Curie research fellow at the National University of Ireland (Ireland, 2009–2011), an associate professor at the Australian National University (Australia, 2015–2019), and a senior research scientist at RIKEN (Japan, 2011–2024). Starting from 2024, he is an Ikerbasque Professor at the Donostia International Physics Center (Spain). His ongoing research areas include: complex wave systems, geometric phases, spin-orbit interactions, wave momentum and angular momentum, wave vortices, wave-matter interactions, etc. He has co-authored more than 130 scientific papers, reviews, and book chapters.
