Physics and Applications of Epsilon-Near-Zero Materials
Robert W. Boyd, University of Ottawa

In this talk, we describe some of the properties of light propagation through a material for which the dielectric permittivity, and hence the refractive index, is nearly vanishing. Among other unusual optical properties, we find that such epsilon-near-zero (ENZ) materials display ... more

2D and 3D SEM-based electron diffraction techniques as central tools for correlative microscopy to obtain new insights into microstructure physics and chemistry
Stefan Zaefferer, Max Planck Institute for Iron Research Duesseldorf
https://www.mpie.de/2890931/microscopy_and_diffraction

The scanning electron microscope (SEM) offers two electron diffraction techniques that allow to obtain comprehensive and quantitative information about the crystalline microstructure of materials, namely electron backscatter diffraction (EBSD) with all its facets and variations, ... more

Amon based Quantum Machine Learning
Anatole von Lilienfeld, University Vienna
https://www.chemspacelab.org/head-of-lab/

Many of the most relevant observables of matter depend explicitly on atomistic and electronic details, rendering a first principles approach to computational materials design mandatory. Alas, even when using high-performance computers, brute force high-throughput screening of mat ... more

Nanoporous materials for hydrogen isotope separation
Dr. Michael Hirscher, Max-Planck-Institut für Intelligente Systeme (ehemals Max-Planck-Institut für Metallforschung), Stuttgart
https://mms.is.mpg.de/research_fields/hydrogen-storage

One of the important operations in chemical industry is separation and purification of gaseous products. Especially H$_2$/D$_2$ isotope separation is a difficult task since its size, shape and thermodynamic properties resemble each other. Porous materials offer two different mech ... more

Quantum magnonics - Quantum optics with magnons
Silvia Viola-Kusminskiy, Max Planck Institute for the Science of Light

In the last five years, a new field has emerged at the intersection between Condensed Matter and Quantum Optics, denominated “Quantum Magnonics”. This field strives to control the elementary excitation of magnetic materials, denominated magnons, to the level of the single quanta, ... more

Laser Picoscopy: Seeing valence electrons in solids with sub-Angstrom resolution
Prof. Dr. Eleftherios Goulielmakis, University of Rostock

The wavelength of visible light is often assumed to impose a fundamental frontier in optical microscopy. Indeed, the Abbe limit constrains the resolution of optical techniques to tens or hundreds of nanometers and makes visible light inadequate for electron-level imaging of the m ... more

Embedded many-body perturbation theory for the electronic properties of organic systems
Xavier Blase, Institut Néel, CNRS, Grenoble, France

Many-body perturbation theories, such as the GW and Bethe-Salpeter formalisms, have become a tool of choice in solid-state physics for studying the optoelectronic properties of crystals. Difficulties arise when attempting to explore with such techniques extended disordered system ... more
