Dark matter problem is one of the fundamental unresolved problems in modern physics. A promising dark matter candidate is provided by axions which are hypothetical particles extremely weakly interacting with the ordinary matter and able to convert to the pair of photons in the external magnetic field.
While the search for cosmic axions is pursued by a number of groups all over the world and the outcome of this research is not known a priori, there exist condensed matter systems described by the equations of axion electrodynamics. Hence, their collective excitations are emergent axions. Such structures can be realized either by breaking the time-reversal symmetry (e.g. Tellegen media) or keeping such symmetry intact. In the latter case, non-reciprocal magneto-electric coupling of the structure is quantized and the material is called topological insulator.
Responsibilities
In this project we will investigate the realizations of axion physics both in condensed matter and photonic structures. During the project, we will collaborate with Nobel Prize winner Prof. Frank Wilczek and publish the obtained results in the most prestigious international journals which enter top-1%: Nature, Science, Nature Photonics, Nature Physics и Nature Communications. This research agenda has been supported by Priority-2030 strategic development program as one of the promising in ITMO University.
