Research in the department of theoretical physics is focused mainly on the issues of the modern string theory, the theory of relativity and the specific problems in quantum theory. Currently, there are several important theoretical physicists, who work not only with scientists on the international stage, but also include doctoral students in their research.

Areas of research

prof. Rikard von Unge, Ph.D.

Prof. Rikard von Unge and his working group focuses primarily on research in supersymmetry and its consequences on physical theories beyond the standard model, such as string theory or supergravity. Moreover, these theories are very often interesting from a purely mathematical point of view. One of the longer-term topic is the study of supersymmetric nonlinear sigma models and their relationship to complex geometry. For example, recently articles on disruption of spontaneous supersymmetry, supergravity on an application for inflation theory were published. Abroad prof. von Unge collaborates with colleagues at a number of universities, especially the This Stony Brook University (USA) and Uppsala University (Sweden).

List of publications

prof. RNDr. Jana Musilová, CSc.

Research activities of prof. Jana Musilová were successively intent on the following topics: low-energy electron diffraction, optical properties of solids, modulation spectroscopy and global analysis and differential geometry. Her work includes mathematical physics, such as calculus of variations on differential manifolds, geometrical approach to the variational problems of higher-order mechanics and field theory, geometrical theory of non-holonomic constraints, symmetries and conservation laws, and physical applications. Prof. Musilová is known also for her work in Physics education and development of Physics teaching not only for university students.

List of publications

prof. Mgr. Tomáš Tyc, Ph.D.

Group of prof. Tomáš Tyc is engaged in research in the field of optics, mainly in two directions. The first is called optics of invisible cloaks and perfect lenses, a very young and modern field, which significantly applies geometry and knowledge of mechanics. The second direction of the research is the development of methods for imaging by multimode optical fibers in cooperation with dr. Tomas Čižmár at the University of Dundee. In both areas they have achieved significant results at international level. They are collaborating with colleagues at a number of universities, especially in Dundee, Glasgow and Exeter (UK), Suzhou (China) and Singapore.

List of publications

doc. Mgr. Josef Klusoň, Ph.D., DSc.

Research interests of dr. Josef Klusoň are extended over broad area of string theory. Past work was dedacated to tachyon dynamics (the problem of the tachyon condensation on unstable D-branes) and the analysis of D-brane probes in various backgrounds. His work included also study of various aspects of string field theory, Berkovit's superstring theory and also the background independent string field theory. Recently he worked on problems considering pure spinor string in AdS5×S5, the classical analysis of the sigma model on supercoset target, the relation between bosonic string in AdS5×S5 and BRST symmetry of the world-sheet theory. In the last two years he has been working on the problems of modified theories of gravity, as for example Hořava-Lifshitz gravity and massive gravity.

List of publications

doc. Franz Hinterleitner, Ph.D.

Dr. Franz Hinterleitner deals with quantum dynamics of the gravitational field in the framework of loop quantum gravity, and the search for observable quantum effects. "Loop quantum gravity" involves quantization of spatial geometry based on Einstein's general theory of relativity. Discretion is a characteristic feature of quantum geometry, ie the occurrence of "atomic" or "grain" of space on the scale of the Planck length. The main problems include the current dynamics of this theory and search for observable effects; it helps to model the flat space with quantum fluctuations, a description of gravitational waves and propagate electromagnetic waves on the background of quantized geometry.

List of publications

Klaus Bering Larsen, Ph.D.

Dr. Klaus Bering is working on various topics in Lagrangian and Hamiltonian field theory, quantum field theory (QFT), topological field theory (TFT), string theory (ST) and string field theory (SFT), in particular the Batalin-Vilkovisky (BV) formulation and supermathematics. His work also includes Fedosov and Kontsevich quantization, sigmamodels, Lie algebroids, amplituhedron and twistor theory.

List of publications

Jörgen Linus Wulff, M.Sc., Ph.D.

Dr. Linus Wulff is interested in string theory, especially to holographic principle. This holographic principle says that physical theory describing phenomena in a given volume can be equally described by a theory that only lives on the surface surrounding this volume. Just as a simple holographic image represents a 3-D scene with a 2-D surface, nature itself can store information about the interior of the area on its surface. Understanding the holographic principle can lead us to a deeper understanding of nature, at the most basic level.
