Professor: Boris Fine
Oleg graduated from the Moscow Institute of Physics and Technology in 2006, and received Candidate of Sciences degree from the Institute for Theoretical and Experimental Physics in 2009. His early research, including his postgraduate studies, was devoted to the theoretical physics of elementary particles and fields and astroparticle physics. In 2012, he moved to Lancaster, UK, to work as a Senior Research Associate at the Physics Department of the Lancaster University on the far-from-equilibrium quantum dynamics of an impurity particle in a one-dimensional quantum fluid. In 2014, he moved back to Moscow to work for the Russian Quantum Center as a member of the Many-body Theory Group. In 2016, he got involved in a project aimed at the development of the Quantum Key Distribution system, a joint venture of a consortium of companies and research centers, including the Russian Quantum Center, DePhAn LLC and Steklov Mathematical Institute of the Russian Academy of Science. In 2017 he moved to Skoltech to work on hight-temperature superconductivity. In June 2017 he acquired a Russian Science Foundation grant.
I am looking for master and PhD students as well as young researchers with a PhD degree to collaborate on the project “Quantum adiabaticity in many-body systems” supported by the Russian Science Foundation. Please do not hesitate to contact me if interested.
