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.
(а) Photonic realization of weak 3D photonic topological insulator. This is not axion topological insulator.
(b) A schematic of axion topological insulator in condensed matter physics. Such structures are not realized in photonics so far.
