Laboratory of Theoretical Physics
|W. Ostwaldi 1, 50411 Tartu
B-wing 3rd floor
We study the problems of high energy physics, theories of gravitation and mathematical physics. The main topics include
- extensions of Einstein's general relativity, geometrical foundations of gravity, theoretical cosmology: geometric foundations of gravity, inflation, dark energy, dark matter;
- phenomenology of electroweak and strong interactions in the Standard Model and beyond, taking into account mass and polarisation effects; group theoretical foundations and chaotic chains;
- relativistic quantum information theory.

Former members (since 1990)
The predecessor of the laboratory was the theoretical physics research group in the Institute of Physics, Mathematics and Mechanics, founded in 1947 under the Estonian Academy of Sciences. In the 1960s the expanding group was called the Sector of Theoretical Physics and Mathematics, then in the Institute of Physics and Astronomy. The Laboratory of Theoretical Physics exists since 1986, in the Institute of Physics, which continued to belong to the Estonian Academy of Sciences until 1997 when it was subsumed into the University of Tartu.
In 2015 a part of the Laboratory/Chair of Field Theory (formerly Chair of Theoretical Physics, Department of Physics, University of Tartu) was joined with Laboratory of Theoretical Physics.
