Valery S. Zapassky , a leading researcher of our laboratory, was awarded the State Prize in the field of science and technology for the creation and development of a new branch of physics - spin noise spectroscopy (together with Evgeniy. B. Aleksandrov, an academician of the Russian Academy of Sciences).Now this area is being rapidly developed not only by our employees, but also by the international scientific community. Spin noise spectroscopy is a new method of physical research that makes it possible to observe the movement of elementary magnets in a medium (atoms, electrons, atomic nuclei, etc.). An important feature of this method is that it does not imply observation of the response of the medium to an external influence, as is usually the case: in order to determine the elasticity of the medium, one must try to deform it, and in order to find out the tone of the sound of the string, its vibrations must be excited. In this analogy, spin noise spectroscopy implies the ability to hear the sound of a string at rest.
Valery S. Zapasskii is one of the potential supervisors of undergraduates and postgraduate students. You can see the proposed work topics on our website (https://solab.spbu.ru/ru/)!

Professor Alexei Kavokin, head of the Spin Optics Laboratory at St. Petersburg State University, became the first Russian scientist in history to be awarded the ISCS 2020 Quantum Devices Award. (spbu.ru)This award recognizes innovative contributions to sophisticated semiconductor and quantum nanostructure devices. The prize was awarded to A.V. Kavokin for predicting Bose-Einstein condensation of excitons and exciton polaritons at room temperature, which made it possible to create polariton lasers.
