In 2018 the work under the projects supported by the Russian Scientific Foundation in the frames of the 2016 and 2017 competitions was completed. The requirements of some of the competitions assumed a possibility of prolongation of the projects for one or two years on a competitive basis. Moreover, the Foundation announced a competition for separate research groups with the beginning of the financial support in 2019.
RSF summarized the results and published the lists of the winners of these competitions. Among them there are eight projects of the Krasnoyarsk Science Center SB RAS.
The following projects and their supervisors became the winners in the competition for separate research groups in 2019:
Andrey Kolovsky, "Quantum transport in optical lattices connected with atomic reservoirs"
Andrey Vjunyshev, "Talbot effect in nonlinear photonics: enhancing nonlinear-optical effects and space modulation of light beams"
The following project and the project supervisors won the competition for the project prolongation for 2019:
Faris Gelmukhanov, "Transfer of energy and charge in molecular systems controlled by strong and weak X-Ray impulses"
Boris Kuznetsov, "Development of new techniques for obtaining valuable chemical products by the method of catalytic depolymerisation of organosolv wood lignin"
Anatoly Lepeshev, "Research of the processes of vacuum-plasma formation of artificial pinning centers in HTSC ceramics and creation on its basis of active elements of power electro technologies of a new generation"
Mikhail Gladyshev, "Revealing genetic and ecological factors determining the content of polyunsaturated fatty acids - protectors of cardiovascular diseases in commercial fish species."
Iosif Gitelzon, "Deciphering the molecular mechanism of bioluminescence in higher fungi and the development of methodological basis of its application for creating a new non patent series of analytical methods for biotechnology and medicine."
Alexander Fyodorov, "Development of new materials, including nanomaterials for their use in thermoelectric converters"
The Talbot effect is a diffraction effect consisting in self-imaging of a periodic diffraction grating at regular distances from an object. This phenomenon has various applications not only in optics, but also in acoustics, electron microscopy, plasmonics, atomic and quantum physics.
"Recently, there has been an interest in this phenomenon due to the fact that this effect is becoming widespread in photolithography, when the image of an arbitrary macroscopic mask is transferred and multiplied at the microscale. Another feature of the Talbot effect is that through this effect it is possible to form images at distances smaller than in the case of using standard lenses, which is an apparent advantage in the development of components of integrated photonics ", explained the scientist. Using the Talbot effect in nonlinear optics can qualitatively transform the processes of nonlinear-optical conversion of light frequency. Therefore, the aim of the claimed project is a systematic study of the combined manifestation of the Talbot effect and nonlinear-optical interactions. The project will result in the development of new physical principles of nonlinear-optical light conversion under the conditions of the Talbot effect and spatial modulation of the generated light beams based on this effect. During the project implementation, a method will be proposed for enhancing images in the Talbot planes, which is of great interest for photolithography and imaging. The results obtained will contribute to the development of the photonic component base to create efficient integrated light devices with specified characteristics.
