Orbitals, spins, lattice, charges and coupling between all of them

The properties of transition metal compounds are largely determined by nontrivial interplay of different degrees of freedom: charge, spin, lattice, and also orbital ones. Especially rich and interesting effects occur in systems with orbital degeneracy. For example, they result in the famous Jahn−Teller effect, leading to a plethora of consequences for static and dynamic properties, including nontrivial quantum effects. In the present talk, we will discuss the main phenomena in the physics of such systems, paying central attention to the novel manifestations of those.

X-ray Photoelectron Spectroscopy: surface analysis.

An important task of studying the properties of materials is surface analysis. The surface plays an important role in the creation of materials with unique electrical, thermal, catalytic, magnetic and many other properties. Electron spectroscopy methods are one of the main methods for studying the physical properties of surfaces, which make it possible to study the electronic properties of solid surfaces and low-dimensional systems formed on them.

Metal-ceramic metamaterials for wireless power transfer applications

Metamaterials are an innovative solution to the development of new approaches to the subject of wireless power transfer (WPT) technologies. In this communication, the design, development and characterization of new structures for wireless power transfer (WPT) applications is presented. These new structures are based on resonant electromagnetic coupled metal-ceramic metamaterials which have shown very efficient medium-distance transfer ratios owing to strong couplings of their electromagnetic resonances. The development and characterization of the WPT prototype will be presented. When the coupling distance of the system is maximized, efficiencies up to 70% at distances comparable to the size of the resonators are achieved at an operating frequency of 250 MHz.

Improving Performance and Stability of Polymer/Perovskite Solar Cells by Using Polymeric Interlayers

Our research group focuses on the development of functional polymer interlayers for various kinds of optoelectronic devices, including thin-film transistor (TFT), (photo-)memory, light-emitting diode (LED), and solar cells. We are particularly interested in exploring the structure-performance relationship of polymers. Besides the advances in controlled synthesis of organic semiconductors, we also explore innovative interfacial and device engineering to optimize the device performance. Herein, we focus on introducing our recent works in polymer/perovskite solar cells. In this presentation, an integrated study of combining interface and device engineering will be first introduced and discussed to explore the full promise of the devices. Afterward, we further translate the knowledge accumulated in OPVs into the emerging organic-inorganic hybrid perovskite solar cells (PVSCs) to develop stable and high-performance devices.

Liquid Metal Dealloying: From Fundamentals to Applications

Dealloying is an efficient method for self-assembling quintillions of nanoscale objects into a macroscopic body (10¹⁸ for 1 cm³ of material with a 10 nm structure size). There are four main types of dealloying methods, namely, electrochemical, liquid metal, solid-state, and vapor phase dealloying. These dealloying methods are complementary to each other and enable researchers to design porous materials of nearly any chemical composition from reactive materials such as magnesium to noble ones such as gold and modern ones such as high-entropy alloys. Among the existing dealloying methods, liquid metal dealloying invented by Prof. Hidemi Kato and co-workers at the Institute for Materials Research, Tohoku University is of particular interest because this enables the synthesis of less noble porous metals. Liquid metal dealloying utilizes metallic melt as a corrosive medium and relies on the difference in enthalpies of mixing between each element of the precursor alloy with the metallic melt. The outstanding functional properties of these materials due to the high surface area envision many opportunities for their application as supercapacitors, battery electrodes, and catalysts.

Theory of itinerant electron magnetism

Magnetic ordering and related phenomena are of essentially quantum and essentially many-body origin and require strong enough electron-electron interactions. Also, they are very sensitive to the details of electronic structure of specific materials. Since practically all magnetic materials are strongly correlated, the conventional tools like density functional can be insufficient. This makes a truly microscopic description of magnetism of real materials a challenging task. I will review contemporary approaches to theory of a specific class of magnetic materials, itinerant-electron magnets.

Modert Theory of Multiferroics: What Is It and How Does It Work?

Multiferroicity is the ability of materials to break the inversion symmetry and thus develop spontaneous electric polarization in response to complex magnetic order. The phenomenon provides a unique possibility for the mutual control of electric and magnetic properties by applying magnetic or electric field, which has tremendous importance for the development of ultra-compact spintronics. In this talk I will discuss key mechanisms of magnetic inversion symmetry breaking and magnetoelectric coupling, originating from interplay between interatomic exchange interactions, intraatomic Hund's coupling, and relativistic spin-orbit coupling.

MgAl₂O₄ ceramics doped with rare earth ions: synthesis and luminescent properties

The choice of a host is a very important stage for developing new luminescent materials. In this case, it is necessary to take into account the physical and chemical properties of the material and the stability under various operational influences. Transparent ceramics based on spinel structure is a good candidate for these requirements. The magnesium aluminate (MgAl2O4) spinel (MAS) is one of the most perspective ceramic materials due to excellent combination of the chemical, thermal, dielectric, mechanical, and optical properties. In this work, undoped MAS and doped with REIs ceramics were prepared by spark plasma sintering technique (SPS). The optimal modes for SPS processing for MAS were justified to achieve the better transparent, luminescent and mechanical properties. In additional, the structure as well as the photoluminescent and time-resolved cathodoluminescent properties of the spinel ceramics were studied. Decay kinetics and nature of luminescence of MAS ceramics doped with REIs are discussed.

Radiation effects and defect in functional oxides and halides for fusion applications

I will present an update survey of the optical properties of primary radiation-induced point defects in alkali halides, simple oxides and some oxide and halide perovskites, with special emphasis of their application in fusion application & radiation imaging and dosimetry. In particular, we discuss in details the optical properties of single electron F and F+ centers in rock-salt (f.c.c.) alkali halides and oxides and show that the Mollwo-Ivey law well-known for the F-type centers in alkali halides may be extended for other rock-salt structure insulators.

From Chicxulub to Chelyabinsk: on the role of physics in the study of shock events

The discovery by Alvarez (winner of the Nobel Prize for research in the field of nuclear physics) of the iridium anomaly at the border of the Cretaceous-Meteorogene led to a revolutionary change in the basic paradigm of traditional geology about the gradualness of geological processes. It turned out that the impact of a 10-km asteroid can change the geological and biological processes on earth within a few minutes.
