PhD student in axion electrodynamics

Dark matter problem is one of the fundamental unresolved mysteries 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 axion topological insulator.

Overview of the results of our group on topological photonics.

Responsibilities

Recently, axion topological insulators were realized in condensed matter physics. However, the implementation of such structures and their experimental investigation are not straightforward. Therefore, realization of axion topological insulators on photonic platform is especially promising. This is exactly the topic of this PhD project. Note that the outlined research agenda has been supported by Priority-2030 strategic development program as one of the most promising in ITMO University.

In this 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.
