Anton Zasedatelev

Professor: Pavlos Lagoudakis

Anton graduated from the Institute of Cryptography, Telecommunications and Computer Science in 2011. His Specialist degree thesis concerned a study of nonlinear optical properties of colloidal quantum dots. In 2012, Anton started his postgraduate research devoted to investigation of physical mechanisms and consequences of light-matter interaction in hybrid exciton-plasmonic systems based on macroheterocyclic chromophores and metal nanostructures. His research focused on photoinduced processes of excitation and relaxation in such systems and paid great attention to their nonlinear optical properties. The research resulted in a series of publications in peer-reviewed journals and formed the core of Anton’s PhD thesis. In June 2016, he successfully defended the thesis at the National Research Nuclear University “MEPhI”.

Since January 2016, Anton is involved in a Skoltech project where he develops thin-film saturable absorbers based on carbon nanomaterials for ultra-fast laser applications. His other research interests also include studies of plasmon-induced photochemical reactions of macroheterocyclic chromophores in hybrid exciton-plasmon systems, with the purpose of finding the ways to considerable enhancement of their photochemical properties in sensor applications.

“Polariton simulators”

Polaritons, composite particles consisting of light and matter, can be created inside semiconductors built into nano-structures of exquisite precision. At low densities and temperatures these particles condense together to form a single quantum state. This physics can be exploited in the realization of the next generation of low threshold lasers. The task of this project is to imprint polariton condensates into multi-site configurations by spatial modulation of the pumping laser and explore the applications such as quantum polariton simulators: highly tunable system that can emulate other, not so easily accessible, quantum systems.
