Ivan Vakarchuk

Ivan Oleksandrovych Vakarchuk (Іван Олександрович Вакарчук; 6 March 1947 – 4 April 2020) was a Soviet-Ukrainian physicist, politician and social activist.

Ivan Vakarchuk was born on 6 March 1947 in the village of Brătușeni, Edineț District, Moldavian SSR.

Ivan Vakarchuk was married, his wife Svetlana (b. 1947) is teacher of physics, assistant professor of Lviv National Stepan Gzhytsky University of Veterinary Medicine and Biotechnology.

In 1965 Vakarchuk received his secondary education by finishing with honours a local middle school in Brătușeni.

In 1965–1970 he studied at the Faculty of Physics at the University of Lviv.

From 1970 to 1973 he continued his studies at postgraduate research (aspirantura) of the Lviv section of condensed state statistical theory of the Institute of Theoretical Physics, affiliated with the Ukrainian Academy of Sciences.

From 1973 to 1984 Ivan Vakarchuk worked at the Lviv branch of the Institute for Theoretical Physics affiliated with the Ukrainian Academy of Sciences (now is the Institute of Condensed Matter Physics of National Academy of Sciences) as junior research fellow, senior researcher and head of quantum statistics department.

In 1974 he defended his candidature thesis "Application of the method of displacements and collective variables in the study of interacting Bose particles near absolute zero", and in 1980 his doctoral thesis "Microscopic theory of Bose liquid".

Ivan Vakarchuk represented the Lviv school of statistical physics founded by Ihor Yukhnovskyi, member of the National Academy of Sciences of Ukraine.

Ivan Vakarchuk has the rank of Doctor of Physical and Mathematical Sciences, Professor, PhD with the thesis: "Application of the method of displacements and collective variables in the study of interacting Bose particles near absolute zero" (Institute for Theoretical Physics, Ukrainian Academy of Sciences, 1974) doctoral thesis on "Microscopic theory of Bose liquid" (Institute for Theoretical Physics, Academy of Sciences of the Soviet Union, 1980).

A distinctive feature of professor Ivan Vakarchuk was the breadth of his scientific interests: physics of quantum liquids, theory of phase transitions and critical phenomena, physics of disordered systems, magnetic systems, mathematical methods in theoretical physics, fundamental problems of quantum mechanics and quantum computer sciences, geophysics, general relativity theory, cosmology, philosophy of science.

In each of these fields he proposed new original approaches to the study of various physical phenomena and processes.

Ivan Vakarchuk paid particular attention to the latest achievements in science and philosophy of science issues, including the relationship between research methods of natural sciences and humanities, identifying common math mechanisms that "manage" the processes occurring in the humanitarian and social spheres.

They had two sons: Svyatoslav Vakarchuk (b. 1975), who was a Ukrainian politician, founder of Holos party and frontman of "Okean Elzy", the famous Ukrainian rock band, and Oleg (b. 1980) - a bank employee.

After 1984, Vakarchuk began performing the duties of Professor, head of department of theoretical physics at the University of Lviv.

From 1990 to 2007 and again between 2010 and 2013 he was rector of the Lviv University.

On 13 November 1990 Ivan Vakarchuk was elected the rector of Lviv University and worked until November 2007.

He is the author of over 240 scientific papers, and author of the books "Lectures on General Relativity" (1991), "Quantum Mechanics" (1998, 2004, 2007, 2012) "Introduction to the many-body problem" (1999) and "The Theory of Stellar Spectra" (2003).

During the 2004' presidential elections, Vakarchuk openly called students to vote for Viktor Yushchenko.

In 2007–2010 he was Minister of Education and Science of Ukraine.

Hero of Ukraine (awarded on 5 March 2007), he was father of the leader of the rock band Okean Elzy Svyatoslav Vakarchuk.

On December 18, 2007 Vakarchuk was appointed the Minister of education and science of Ukraine.

In 2008 he took the 50th place in the Top 100 of the most influential Ukrainians, according to Reporter magazine.

Later he held this office again between 2010 and 2013.

Vakarchuk died on 4 April 2020, at the age of 73 in Lviv.

The cause of death was not reported.
