Open RQC colloquium. Lecture 27


The Twenty Seventh lecture "Quantum Physics for Materials Science: from Fundamental Discoveries to Advanced Materials" in Open RQC Colloquium will be held in National University of Science and Technology MISIS (Moscow, Leninskiy prospekt 4) lecture hall № Б-536 (5th floor), on 23th of June 2017 at 10:00 a.m by Igor Abrikosov, a member of the Royal Swedish Academy of Sciences, Head of Theoretical Physics Division at Linköping University, Sweden, and Scientific Leader of Materials Modeling and Development Laboratory at National University of Science and Technology ’MISIS’, Moscow, Russia.

Abstract

Starting at the most fundamental level of quantum physics, we extend theoretical perspectives, e.g. via studies of matter at extreme conditions and employ the generated knowledge for a design of novel advanced materials. We present efficient theoretical tools for materials modeling at different time and length scales, with capabilities well beyond state-of-the-art software. We apply the theory in studies of metallic Os compressed to pressure 750 GPa, or twice the pressure in the Earth’s core, followed by a discovery of a novel type of electronic phase transition, the core-level crossing transition [1]. We explain the absence of thermal expansion in Fe-Ni alloys, the so-called Invar effect [2], followed by a discovery of the pressure-induced invar effect [3]. We demonstrate that universality of our theoretical approach allows us to study very different systems, from materials relevant for quantum technology [4] to industrial alloys for hard-coating applications [5]. We therefore promote a paradigm shift from the predominantly empirical approach within materials development towards the knowledge-based materials design inspired by theory. The capabilities of the latter is illustrated with a discovery of the first magnetic MAX-phase [6].

Biography

Professor Abrikosov is a member of the Royal Swedish Academy of Sciences, Head of Theoretical Physics Division at Linköping University, Sweden, and Scientific Leader of Materials Modeling and Development Laboratory at National University of Science and Technology ’MISIS’, Moscow, Russia. He studies materials at the most fundamental level of physics., developing quantitative theory of solids with sufficient predictive power for the knowledge-based materials design. His research area covers a broad spectrum of fundamental problems within the theoretical solid-state physics, ranging from methodological developmental work to advanced applications for new classes of materials and challenging phenomena, such as materials with complex magnetism and magnetic phase transitions, nanostructured materials, materials for fuel cell applications, and behavior of solids at extreme conditions. Scientific approach of Prof. Abrikosov includes numerous collaborations with leading experimental environments. He has published more than 270 papers (h-index 47), including publications in journals with very high impact factor, like Nature and Science. He gives invited presentations at leading international conferences, such as APS, MRS, TMS and DPG annual meetings. Prof. Abrikosov received prestigious awards, Oscar prize in 2000 and Göran Gustafsson Prize in Physics in 2007.
