Spin Optics Research Laboratory named after I. N. Uraltsev
This laboratory was established as part of a scientific research project supported with a monetary grant awarded by the Government of the Russian Federation under a grant competition designed to provide governmental support to scientific research projects implemented under the supervision of the world's leading scientists at Russian institutions of higher learning (Resolution of the RF Government No.220 of April 9, 2010).
Grant Agreement No.: 11.G34.31.0067
Name of the institution of higher learning:
Federal state budget educational institution of higher professional learning "St. Petersburg State University"
Fields of scientific research:
Nanotechnologies. Semiconductor-based nanostructures and microresonators as basic components of new-generation information devices.
To develop new provisions of the dynamic theory of superconductive phase transitions in microresonators.
Key project objectives:
1. To measure photo-induced Raman effect and terahertz adsorption in specially grown microresonators and achieve separation between the superconductive and normal fractions of polariton gas.
2. To determine the mechanism of formation of polariton Bose-Einstein condensate and the possibility of a Berezinsky-Kosterlitz-Thouless transition occurring in microresonators when conducting Faraday/Kerr rotation experiments by subjecting polarizing noise to spectroscopy.
3. To monitor the threshold between diffusional and superconductive proliferation of a polariton pseudospin.
4. To design the concepts of new devices based on the new physical effects accounted for by light-induced spin transport.
Anticipated scientific outcomes:
The project will enable the St. Petersburg State University to create a new technological company on the basis of the Spin Optics Research Laboratory named after I. N. Uraltsev.
