On September 1, 2023, we hosted Professor Klaus von Klitzing at the Institute – the Nobel Prize winner in Physics “for the discovery of the quantized Hall effect”. During the meeting, our researchers had the opportunity to take part in a conversation with the eminent guest, talk about research conducted at the Institute, and listen to a short presentation by Prof. von Klitzing. The meeting took place in a great atmosphere, conducive to interesting discussions and information exchange. We would like to thank the world-renowned scientist for his time and interest in our Institute. We would also like to thank everyone who was involved in the organization of this unique event.
