Specialist in non-linear photonics; member of the European Technology Platform "Photonics21". The key research works of Sergey K. Turitsyn are focused on nonlinear wave processes and solitons in optical fibers, self-focusing of laser beams, high-speed fiber-optic telecommunications, fiber lasers. Sergey K. Turitsyn was a fellow of the Royal society ( UK). In 2013, he won the mega-grant competition and created the laboratory of nonlinear Photonics at NSU.

Areas of research done by Kobtsev include the investigation of fiber lasers with mode emission. His key achievements are: the acquisition of new knowledge about the physics of generation of these lasers and nonlinear conversion of pulses, and obtaining the record parameters of the radiation of these lasers. Sergey M. Kobtsev proposed a new experimental approach to the study of the dynamics of fiber lasers; he first discovered and studied the spatio-temporal regimes of laser generation. For the first time, the synchronization of mod radiation in extra-long fiber lasers was implemented, and the record-high energy of pulses without the use of additional amplifiers was achieved. Besides, Sergey Kobtsev is the founder and the head of the group of companies "Tekhnoscan" (startups of Novosibirsk State University). Our laser systems are supplied to many renowned organizations of the world, including large nuclear centers, metrology centers and research institutes of multinational companies. The most famous products of the Technoscan companies on the market are the continuous single-frequency titanium-sapphire lasers with a narrow emission line.

A specialist in the field of physics such as: Rydberg atoms, atomic spectroscopy and quantum informatics. He is the author of over 40 scientific papers. Studied the process of collisional ionization and photoionization thermal radiation of highly excited atoms, developed the original scheme of quantum logic operations based on the adiabatic passage in ensembles of interacting atoms. He participated in experimental studies of the resonant dipole-dipole interaction of single ultracold atoms. The winner of the RF Presidential grants for young PhDs in 2010 and 2012; the winner of the scholarship fund "Dynasty" in 2008-2011.

Specialist in particle physics. Participated in experiments on colliding electron-positron beams, such as MD-1 and KEDR at VEPP-4, CMD-2 at VEPP-2M in Novosibirsk, and Belle B-factory in KEK, Japan. Proposed and successfully implemented a spectrometer for the VEPP-4M with the unique energy resolution for registering scattered electrons; has developed the method of creating electromagnetic calorimeters on the basis of the crystals of cesium iodide, which are now successfully used in a number of experiments. Head of the research group actively involved in the international project Belle (studying the phenomenon of nonconservation of combined (CP) parity in the decays of B mesons).

Specialist in the field of transport phenomena in semiconductor nanostructures. The main papers are devoted to classical and quantum electron transport in mesoscopic systems with atwo-dimensional electron gas in semiconductor heterostructures, including quantum Hall effect, universal conductance and thermopower fluctuations, as well as dynamical chaos in solid-sate realizations of Sinai billiards. The leader of research group studying nanoelectromechanical systems based on suspended semiconductor heterostructures with a two-dimensional electron gas.

Taichenachev is a well-known specialist in the fields of high-resolution laser spectroscopy, laser cooling and trapping, frequency standards, quantum and nonlinear optics of resonant media. The most prominent results are as follows: he found the steady-state of atoms in resonance elliptically polarized field; the theory of coherent population trapping was developed for degenerate atomic systems, including the cases of excitation by quantized electromagnetic field and by polychromatic radiation; he proposed and investigated new methods of deep laser cooling of atoms in optical lattices; he found new schemes for excitation of high-contrast super-narrow dark resonances for atomic clocks and magnetometers; he developed several new methods of precision laser spectroscopy of ultracold atoms and ions (magneto-induced spectroscopy, hyper-Ramsey spectroscopy, synthetic frequency protocols etc.), that have led to practical implementation of optical frequency standards with unprecedented stability and accuracy. Alexey Taichenachev is a director of Institute of Laser Physics SB RAS, the leading organization in the field of modern optical frequency standards based on ultracold atoms and ions.
