Academic Career - an overview

Prof. Józef Spałek is Professor of Physics in Department of Condensed Matter Theory and Nanophysics in the Institute of Theoretical Physics of the Jagiellonian University, in Kraków. His postdoctoral work was carried out in England (at Imperial College of Science, Technology, and Medicine), in USA (at Purdue University), and in France (CNRS, Université Paris-Sud, and Université Paris-Nord). He was also a visiting professor at Purdue University (1988-1990), visiting scholar at Harvard University (1995-1996), and professor at Warsaw University (1991-1998). His research interests are concentrated on quantum materials with strongly correlated electrons and in particular, on theory of high temperature ad heavy-fermion superconductivity. He is also interested in nanophysics. In both topics he an original theoretical approach taking into account the strong correlations among the electrons. Recently, he has become interested also in the subject of emergent phenomena in Nature and related philosophical questions. He published over 300 scientific papers and a number of chapters in specialized monographs.

For his work he was awarded the Maria Skłodowska-Curie Prize of the Polish Academy of Sciences in 1997 and a special fellowship from the Foundation for Polish Science in the years 2003-2007. He is a foreign member of Accademia di Scienze e Lettere based in Milano since 2006. In 2005, Professor Spałek received the Polish Order of Merit, the Polonia Restituta Cross from the President of Poland. He was also awarded the Alessandro Volta Silver Medal by Universita di Pavia for his work for the School "European Doctorate in Physics". In the period 2004-10 he was a member of the Science Council to the Minister of Science and Higher Education. For the years 2011-15 he has received a special grant TEAM from the Foundation for Polish Science (FNP). He is also recipient of a prestigous Grant MAESTRO for the years 2012-18 from the National Science Centre (NCN). In 2016 he received the two highest awards in science: the Foundation for Polish Science Prize and Prime Minister Award. In 2019 he received The Marian Smoluchowski Medal in Science, the highest award of the Polish Physical Society. Also, in the same year he has become a member of Academia Europaea. In 2020 he has been elected as corresponding member of the Polish Academy of Sciences.

  • Derived the model now known as t-J model, used extensively in high-temperature superconductivity theory.
  • Provided theory of bound magnetic polaron, which included for the first time the effect of thermodynamic fluctuations of spins on its quantum states.
  • Constructed the thermodynamic model of the metal-insulator transition within the so-called Gutzwiller (mean-field) approach to the correlated electron systems.
  • Discovered the spin dependence of particle mass in correlated systems, which subsequently was experimentally observed in 2005 by Cambridge/Grenoble group.
  • Predicted a new type of quantum critical point (at the border Kondo insulator - non-Fermi liquid).
  • Proposed a new mechanism of spin-triplet pairing based on the Hund's rule exchange.
  • Proposed a new method of calculating electronic properties of nanoscopic systems, based on the exact diagonalization combined with the ab initio approach (EDABI method).
  • At present: Has formulated (2013-now) a unified theory of high-temperature and heavy fermion superconductivity based on the extension of the renormalized mean field theory (Diagramatic Expansion of the Gutzwiller Wave Function and extended to include quantum spin and charge fluctuations), developed together with his coworkers: J. Kaczmarczyk, J Buenemann, M. Zegrodnik, and M. Fidrysiak.
  • Applied his EDABI method to the problem of metallization of molecular hydrogen under pressure, developed with A. Kądzielawa and A. Biborski.
