The 20th National Conference on Superconductivity "New Phases, Concepts, and Advances" was held in Lublin from 22nd to 26th May 2022 as a fully in-person event. The conference was organized jointly by Marie Curie-Skłodowska University, the Lublin Branch of the Polish Physical Society, and the Technical University of Lublin. Former conferences in this series were devoted initially to high-temperature superconductivity and later on, they have included several related phenomena, for example: colossal magnetoresistance, strongly correlated systems, spin and charge ordering, unconventional superconductivity, and other emergent phenomena.

This Conference focussed on topics such as high-temperature superconductors and other highly correlated systems, synergy of magnetism with superconductivity in hybrid structures, critical phenomena in superconductors and superfluids, exotic quasiparticles in topological states of matter, dynamic effects in non-equilibrium superconducting structures, and applications of conventional and unconventional superconductors. The Conference was attended by 76 participants. The opening talk was delivered by Professor Wiesław I. Gruszecki, Vice-Rector of M. Curie-Skłodowska University, who addressed important aspects concerning the retina of the human eye (Dlaczego warto zadbać, aby żółta plamka w naszym oku była naprawdę żółta). Three plenary lectures were delivered by the Professors: Józef Spałek (A brief perspective in high temperature superconductivity), Marta Z. Cieplak (Interplay of various order parameters and disorder in iron chalcogenides), and Tomasz Dietl (Exchange interactions in magnetically doped semiconductors). Also, 20 invited lectures, 23 brief contributed talks, and 23 posters were presented. The list of all presentations, along with their abstracts and a detailed time-frame, is available on the conference webpage (see

We would like to thank all the attendees for their participation and for creating an exciting scientific atmosphere during the Conference. The next event of this series will be organized by colleagues from Cracow.
