IAC Project 'The Influence of Competing Interactions and Topology on the Critical Parameters of Modern Superconducting Materials'

A joint fundamental research project has been established by the Centre for Quantum Metamaterials at MIEM HSE and the Institute of Physics at the Federal University of Rio de Janeiro.

Our scientific partner is the Institute of Physics of the Federal University of Rio de Janeiro, the oldest university in Brazil, founded in 1792. It ranks among the top four universities in the country and is one of the largest higher education institutions. The Institute of Physics at the University of Rio de Janeiro was founded in 1964 and is engaged in research and teaching.

The research is coordinated on the Brazilian side by Prof. Mauro Doria of the Institute of Physics, and on the Russian side by Prof. Arkady Shanenko, Chief Research Fellow of the Centre for Quantum Metamaterials.

The research by Russian and Brazilian scientists focuses on the study of advanced materials for superconducting electronics.

The seminar is the second of two consecutive seminars dedicated to the problem of the connection of the Abrikosov-Bogomolny equations with the physics of topological effects. While the first seminar focused on the classical scalar case and laid the foundation for understanding self-dual vortex structures in type II superconductors, this seminar explores the Abrikosov-Bogomolny equations with the inclusion of spin degrees of freedom. The speaker: Mauro Doria, a member of the IAS project and a professor at the Federal University of Rio de Janeiro.

This is the first of two consecutive seminars on the problem of the Abrikosov-Bogomolny equations and their connection with topological phenomena. The seminar was devoted to the consideration of the Abrikosov-Bogomolny equations in the spinless (scalar) mode, which operate in 2nd-order superconductors near the upper critical field and in the crossover region between 2nd- and 1st-order superconductivity.The focus of the seminar is to obtain the Abrikosov-Bogomolny equations from the kinetic energy of a Schrödinger scalar field by decomposing this energy into three parts, which is known as a special case of the Laplace operator representation through the Lichnerowicz Laplace operator and leads to a local relation between the magnetic induction and the superconducting order parameter.

The symposium was held in Nizhny Novgorod March 9- 13, 2026, and brought together more than six hundred scientists from Russia and other countries. It was the largest condensed matter physics conference in Russia, covering a wide range of topics in the physics of superconducting, magnetic, and semiconductor systems, multilayer X-ray optics, and quantum technologies. The results reached by Senior Researcher Marychev P.M. and Chief Researcher Shanenko A.A. and presented in the Poster were highly regarded by the participants.
