Dr. Mauro M.Doria, professor at the Federal University of Rio de Janeiro, presented the description of topological insulators within the framework of the Abrikosov-Bogomolny equation. The presentation took place at the online seminar of the International Academic Cooperation Project
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.

Poster presentation "The Influence of Interband Scattering on the Intertype Mode in Dirty Two-Band Superconductors" was presented by a Senior Researcher of the Center for Quantum MetamaterialsIAC Project at the XXX Symposium on Nanophysics and Nanoelectronics.
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.
A Participant of the IAC project, Professor Mauro M.Doria, has published the book ONE STEP TO QUANTUM MECHANICS (Mauro M. Doria, Ph.D., Yale University 1983, Full Professor, Institute of Physics, Federal University of Rio de Janeiro, Brazil (452 pages 33 Chapters, in portuguese)
The book is specially focused on the period that precedes the discovery of Quantum Mechanics that now, in 2025, completes one hundred years.
