Grant Agreement No.:
14.Y26.31.0007

Name of the institution of higher learning:
Moscow Institute of Physics and Technology (State University)

Fields of scientific research:
Physical Sciences

Project goal:
To obtain world-class scientific research results in the study of topological quantum phenomena within contacts between superconductors and semiconducting and ferromagnetic nanowires, to publish the research results in the leading Russian and international journals, and to design new quantum-mechanical devices. The project entails training of specialists in quantum nanophysics at the Moscow Institute of Physics and Technology, as well as collaborating with Russian and foreign scientists in pursuit of ongoing development of Russian science, education and high technologies.

Project objectives: 
The project entails theoretical and experimental investigation of the fundamental physical properties of hybrid superconducting nanostructures, including development of the quantitative microscopic theory of quantum processes within those systems and its comparison with the outcomes of experiments in tunnelling, electronic transport, nuclear-powered and high frequency spectroscopy. The objects of the research will include metallic and semiconducting nanostructures created on the basis of superconductors conjoined with so-called topological insulators.

 

Leading Scientist

 

Leading scientist's full name: Golubov, Alexander Avraamovich

Link to the scientist's profile

Academic degree and title:
Doctor of Physics and Mathematics, Professor

Job title:
Professor, Faculty of Science and Technology, University of Twente (The
Netherlands)

Fields of scientific interests:
Physics of condensed state:
- transport and high-frequency properties of superconductors;
- proximity and Josephson effects;
- quantum processes in electronic and magnetic devices.
Of late, the leading scientist has been investigating topological phenomena in solid bodies, particularly, in superconducting hybrid structures.

Scientific recognition: 
The leading scientist has obtained fundamental results in the field of mesoscopic superconductivity, as well as "superconductor – normal metal" and "superconductor – ferromagnetic" hybrid structures.
He was the first to predict the existence of a gap within the spectrum of excitation of a normal metal in the conditions of its proximity of a superconductor. The results found practical application in the development of superconducting sensors. The theoretical work carried out in the field of "superconductor – ferromagnetic" structures that resulted in the development of the theory of Josephson pi-contacts laid down the foundation for the development of superconducting spintronics.

The leading scientist has made a substantial contribution to the development of the theory of multi-zone and anisotropic superconductors and its applications to new superconducting materials, such as cuprates, magnesium diboride, and ferriferous pnictides.
