George Japaridze

Direction:Physics (physics of condensed environments, nanophysics)
Position:Full Professor

In 1975, George Japaridze graduated from the Faculty of Physics of the Tbilisi State University. Since 1975, his scientific career is connected with the Institute of Physics of the Georgian Academy of Science, where he worked his way from a PhD student to the chairman of the Science Council of the Institute. In 1978, he defended his candidate’s thesis on the topic: “Magnetic properties of one-dimensional fermionic systems. Exactly solvable models”, and in 1998 – a doctoral dissertation on the topic: “Unusual models of low-dimensional magnetism and superconductivity”. In years 1991-2015, he has been intensively collaborating with colleagues from the Institutes of Theoretical Physics of the Universities of Cologne, Fribourg (Switzerland) and Gothenburg and from the Institute of Correlated Electrons and Magnetism of the University of Augsburg and spent considerable time in European research centers. In 2001 G. Japaridze was elected as a corresponding member and in 2013 as a full member of the Georgian National Academy of Science. Since 2019, he has been the Academician-Secretary of the Mathematics and Physics Department of the Academy.
