Division of Theoretical Physics

The scientific activities of the Division include theoretical investigations in high-energy particle physics, general and mathematical physics, astroparticle physics and cosmology, and condensed matter physics. The staff, consisting of 18 researchers with eight postdocs and students, is also involved in undergraduate and graduate studies at universities in Croatia, primarily at the University of Zagreb.

Sixty years ago, when the Ruđer Bošković Institute was founded, the Theoretical Physics Department was its first department, later renamed the Division of Theoretical Physics.

From the very beginning, a close relationship between the Theoretical Physics Department and its counterpart at the University of Zagreb was established and has since proved to be very successful in both research and teaching. Currently, 11 professors at universities in Croatia are former members of the Division of Theoretical Physics. Former members of the Division are also employed in engineering, banks, insurance companies etc., mostly in the United States.

Current research performed in the Division is mainly theoretical high-energy physics (particle physics, general and mathematical physics, astroparticle physics and cosmology) and condensed matter. Recently, the Theory Group has embarked on a new research direction in the field of complex networks.

The staff, consisting of 18 researchers with eight postdocs and students, is also involved in undergraduate and graduate studies at universities in Croatia, primarily at the University of Zagreb.

The main research topics of the group are heavy-quark physics, perturbative quantum chromodynamics (pQCD), gravity and cosmology.
