VI International Conference «Statistical Physics: Theory and Computer Simulations»

Between 27 and 29 August 2025, the 6th International Conference “Statistical Physics: Theory and Computer Simulations” was held in Lviv. The event was organised by the Yukhnovskii Institute for Condensed Matter Physics of the National Academy of Sciences of Ukraine, jointly with the Lviv Polytechnic National University and Ivan Franko National University of Lviv, with the support of the Lviv City Council.

This conference continued the tradition of regular international meetings on statistical physics in Ukraine, which originated in the 1970s and was revived under the title “Statistical Physics” (Lviv, 2005; Kharkiv, 2006; Lviv, 2009; Lviv, 2012; and Lviv, 2019).

This year’s event held special significance, as it was dedicated to the 100th anniversary of Academician Ihor Yukhnovskii, an outstanding Ukrainian physicist, founder of the Lviv School of Statistical Physics and the Institute for Condensed Matter Physics of the National Academy of Sciences of Ukraine, which since July 2025 has borne his name.

At the opening ceremony, welcome addresses were delivered by Director of the Yukhnovskii Institute for Condensed Matter Physics of the NAS of Ukraine Corresponding Member of the National Academy of Sciences of Ukraine Taras Bryk , President of the National Academy of Sciences of Ukraine Academician Anatoliy Zahorodniy, First Deputy Mayor of Lviv Mr Andriy Moskalenko, Deputy Head of the Lviv Regional Military Administration Mr Oleksandr Kulepin, Vice-Rector of the Lviv Polytechnic National University Prof. Roman Korzh, and First Vice-Rector of the Ivan Franko National University of Lviv Prof. Andrii Hukaliuk. The opening ceremony concluded with the presentation of Honorary Doctor Diplomas of the Yukhnovskii Institute for Condensed Matter Physics of the NAS of Ukraine to Prof. Jurij Kozicki (Maria Curie-Skłodowska University, Poland) and Dr Orest Pizio (National Autonomous University of Mexico, Mexico).

Over the three days of the conference, 22 plenary lectures, 32 keynote and oral presentations, and 48 poster sessions were delivered, covering both fundamental achievements and practical applications. Particularly engaging were the in-person plenary talks, including: Prof. Giovanni Ciccotti (Sapienza University of Rome), who spoke about computer simulations and the hydrodynamic limit of the scattering function using non-equilibrium molecular dynamics methods, Academician Alexander Kordyuk (Kyiv Academic University, NAS of Ukraine), who presented research on discovering new quantum materials, Corresponding Member Myroslav Holovko (Yukhnovskii Institute for Condensed Matter Physics, NAS of Ukraine), one of Yukhnovskii’s first students, who gave a talk on the contribution of Yukhnovskii to the statistical theory of electrolyte solutions, Prof. Jurij Kozicki (Maria Curie-Skłodowska University, Poland), who discussed half a century of Yukhnovskii’s theory of the critical point, and Dr Orest Pizio (National Autonomous University of Mexico), who presented on modelling water adsorption on solid surfaces. A talk of exceptional scientific and memorial value was given by Prof. Werner Ebeling (Humboldt University of Berlin), who spoke about the statistical theory of systems of charged particles and the scientific collaboration between Lviv and Rostock that he and Ihor Yukhnovskii developed in the 1960s–1970s. Other notable contributions were presented by Anatoly Belonoshko (Nanjing University, China), Viktor Dotsenko (Sorbonne University, Paris), Ari Seitsonen (École Normale Supérieure, Paris), Mykola Lebovka (F.D. Ovcharenko Institute of Biocolloidal Chemistry, NAS of Ukraine), Prof. Volodymyr Tkachuk (Ivan Franko National University of Lviv), and leading scientists from the Bogolyubov Institute for Theoretical Physics of the NAS of Ukraine – Serhiy Perepelytsya, Larysa Bryzhyk, Yaroslav Zolotaryuk, and Serhiy Sharapov. All speakers participated in the conference in person.

As a means of supporting and encouraging young researchers, a competition for the best poster presentation was held, resulting in the recognition of five outstanding posters. This year’s conference successfully combined in-person and on-line formats (with 16 online speakers), which broadened international participation and ensured an inclusive scientific discussion regardless of geographical boundaries.

We express our sincere gratitude to all participants, speakers, and organisers for their valuable contributions and active involvement. The 6th International Conference “Statistical Physics: Theory and Computer Simulations” once again demonstrated the importance of open scientific dialogue and collaboration in addressing complex challenges in physics and related disciplines.
