The entire range of scientific research of the Center was presented at the "8th International Conference on Superconductivity and Magnetism ICSM 2023" in Turkey
The scientists of the Centre for Quantum Metamaterials , Professors A. Shanenko, M. Croitoru and A. Krasavin, and PhD students A. Lukyanov and V. Neverov took part in the international conference "8th Conference on Superconductivity and Magnetism ICSM2023", held in Fethiye (Turkey) , May 4-11, 2023.
The scientists used the Conference to discuss a wide range of the research projects conducted at the Centre with their colleagues from around the world . Our reasearchers presented a series of 6 reports (5 of them invited) to publicize the results obtained in the past 2 years.
Prof. Shanenko made 2 presentations. In the first, he discussed a new work concluded together with colleagues from the Moscow Institute of Physics and Technology, the Sorbonne University (France) and the Federal University of Pernambuco (Brazil). It was shown in this work that when the temperature is lowered, ferromagnetic superconductors undergo a transition between different superconductivity types, accompanied by the formation of complex spatial structures of a penetrating magnetic flux.
The second presentation of Prof. Shanenko was about a work done in collaboration with colleagues from the University of Camerino (Italy). It was focusing on the study of a novel mechanism of high-temperature superconductivity in multiband superconductors. The results revealed that a very high superconducting transition temperature can be achieved in multiband superconductors, which was previously thought to be impossible.
In his first presentation, Prof. Croitoru outlined the results of a joint study with colleagues from Brazil, where they investigated superconductivity at sample boundaries. This study led to a completely new look at the role of the boundary effects for superconductivity in real materials.
The second presentation of Prof. Croitoru ws dedicated to the study, performed jointly with colleagues from the Nizhny Novgorod University and the University of Bordeaux (France). The study was devoted to find the ways to change the superconducting state by pumping it with microwave radiation. This work is of great interest for possible applications in superconducting electronics.
Prof. Krasavin presented results of a study of the role of correlations in the distribution of impurities in superconductors, in the case when the impurity concentration is high. The results of this study have been recently published in the prestigious journal Communications Physics. It was demonstrated that the presence of such correlations leads to very large changes in the superconducting properties of materials.
The Centres' Interns, PhD students A. Lukyanov and V. Neverov gave poster presentations, in which they clarify the details of the study of correlated impurities in superconducting materials. They gave details of the used computational method that was developed at the Centre.
