SCIENTISTS FROM THE HIGHER SCHOOL OF ECONOMICS AND BRAZIL ARE CREATING A NEW THEORY OF HIGH-TEMPERATURE SUPERCONDUCTIVITY

The Russian and Brazilian scientists have started the joint development of a new theory of high-temperature superconductivity, which will explain the nature of recently discovered superconductors with multiple condensates, as well as the so-called topological superconductors. Mauro Doria, Professor at the Federal University of Rio de Janeiro, and Alexey Vagov, Director of the Center for Quantum Metamaterials at the Higher School of Economics, told HSE Daily about how cooperation will develop.

Centre for Quantum Metamaterials - 2023 Results

11 scientific articles have been published in Q1 journals, including Nature Physics and Physical Review Letters. The research results were also presented in 17 reports at leading international scientific (scientific and practical) conferences in the Russian Federation and abroad.

Artificial atoms in graphene and their collapse

At a seminar held for staff, graduate students and students of the HSE, as well as for everyone, Professor Peeters told about a very interesting phenomenon – the collapse of atoms

The Intern of the Center, Postgraduate Student Vyacheslav Neverov, Made a Presentation at the XXVII International Scientific Conference of Young Scientists

Vyacheslav Neverov made a presentati  "Superconducting transition from type I to type II from the point of view of microscopic theories" at the XXVII International scientific conference of young scientists. The conference was held on the basis of the Joint Institute for Nuclear Research" - a large research center in the city of Dubna near Moscow. Traditionally, this conference gathers young scientists to discuss their research on a variety of topics related to physics and mathematics. The conference provides an opportunity for the young scientists at the beginning of their career to gain the necessary experience of speaking to a large audience and, also, communicating with colleagues.

Progress in the cooperation between the Centre and Brazilian research institutions.

Joint research is aimed at the theoretical description of a new generation of superconducting materials and devices. Among them is the work on the magnetic response of ferromagnetic superconductors, which offers a fresh look at the phenomenon of intermediate or intertype superconductivity in various materials. Another interesting work concerns the new mechanism of the "origin of complexity from simplicity" - when a system with rather primitive interactions between its constituent parts allows the emergence of complex spatial and temporal configurations (patterns). The  article with these results were sent respectively to the editors of the prestigious journals Communications Physics and Physical Review X.

Professor Mauro Doria and Director of the Centre Alexey Vagov talked to TASS journalists

Theoretical physicists from Russia and Brazil are working together on a theory that describes novel superconducting materials with potentially high critical temperature. The theory can explain many properties of superconductors with non-trivial topological properties as well as of those with multiple condensates. This was stated to TASS by professor Dr. Mauro Doria (Institute of Physics at the Federal University of Rio-de-Janeiro, Brazil) and professor Dr. Alexei Vagov (Center for Quantum Metamaterials, Moscow Institute for Electronics and Mathematics, HSE University).

Dr. Mauro Doria, recognized specialist in the field of new superconducting materials, has held an interesting scientific event for all MIEM employees and students - a lecture "The Origin of the Dirac Linear Spectrum and Topology "

Professor Dr. Mauro Doria, from the Federal University of Rio de Janeiro, has visited the Center for Quantum Metamaterials, June 2-10,2023.

The main goal of this scientific visit was a joint research with scientists working at the Center, in particular, with Professor A. Shanenko and Professor A. Vagov. Professor Doria has also given a seminar at the MIEM HSE, where he  talked about his recent work on new materials with non-trivial topological properties.
