Our research

We are a part of the team at the Department of theoretical physics at the Faculty of mathematics, physics and informatics of the Comenius University in Bratislava. Our colleagues work on the topics from particle physics, gravitation and cosmology.

Topics

For decades, scientists have been looking for a unified theory of all fundamental forces of nature. Even though there have been many important and illuminating ideas, the final answer to this question is still out of sight.
We are however sure that at the scales where both the quantum phenomena and curvature of the space time play a significant role, our standard physical notions and approaches need to be changed.
Our team works on topics related to the search of these new notions and approaches. Most notably problems in noncommutative geometry, fuzzy field theory and mathematical objects in the formulation of string theory.
