Everything is Topological

An international research team has discovered that topological electronic states are present in nearly every known material for every electron in the crystal configuration. Appearing this week in Science, the team’s discovery of ubiquitous band topology has motivated re-examining previous experimental data for overlooked topological features, and suggests that the century-old field of band theory should be restructured, with topology joining chemistry and geometry on equal footing.

Spintronic goes chiral<br /><br /><br /> 

Spintronic devices are based on using the fundamental spin of electrons to carry and store information. Their use would not require charge currents for their operation and would lead to improved energy efficiency with lower power consumption, higher data processing speed and better integration of memory and logic. However, suitable materials for new spintronic implementations are needed. Their fabrication as well as analysis require state-of-the-art methods from nanotechnology. This is why researchers of the Max Planck Institute for Chemical Physics of Solids and the Fraunhofer Institute for Photonic Microsystems IPMS have launched a joint project to investigate novel materials for spintronics. The project is being funded by Sächsische Aufbaubank.

The interplay between Topology and Magnetism has a bright future

The new review paper on magnetic topological materials of Andrei Bernevig, Princeton University, USA, Haim Beidenkopf, Weizmann Institute of Science, Israel, and Claudia Felser, Max Planck Institute of Chemical Physics of Solids, Dresden, Germany, introduces the new theoretical concept that interweave magnetism and topology. It identifies and surveys potential new magnetic topological materials, mentions their possible future applications in spin and quantum electronics and as materials for efficient energy conversion. more

<h4>Discovery of New Solid Catalysts for Water Electrolysis</h4>

Green hydrogen - produced from water electrolysis by using sustainable electricity - is getting more attention due to its potential to be used as energy carrier as well as building block for various industrial processes. Among both half-reactions of water electrolysis, Oxygen Evolution Reaction (OER) is kinetically more challenging and it requires advances in the development of innovative electrocatalysts. more

A charge-density-wave topological semimetal

Topological materials are characterised by unique electronic and physical properties that are determined by the underlying topology of their electronic systems. Scientists from the Max Planck Institutes for Microstructure Physics (Halle) and for Chemical Physics of Solids (Dresden) have now discovered that (TaSe4)2I is the first material in which a charge density wave induces a phase transition between the semimetal to insulator state. more

<span class="free_area0_p8 endline itemHeadline">Topological control by tuning structural chirality</span>

Chiral crystals that have a distinct handedness have recently emerged as one of  the most exciting new classes of topological materials. An international research team from institutions in Germany, Switzerland, United Kingdom, and China has now demonstrated that their crystal handedness directly determines how quasiparticles propagate and scatter at impurities in such materials. The study, published in the journal Nature Communications, represents a significant advance towards novel chiral electronic devices. more

<p>Cherned up to the maximum</p>

In topological materials, electrons can display behaviour that is fundamentally different from that in ‘conventional’ matter, and the magnitude of many such ‘exotic’ phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached — and controlled — in a real material. more

<div style="text-align: center;">A fresh twist in chiral topology</div>

Electrons in “chiral crystals”, solid-state materials with definite “handedness”, can behave in unexpected ways. An interdisciplinary team from research institutions in Germany and China has realized now a theoretically predicted peculiar electronic state in a chiral compound, PtGa, from the class of topological materials. The study which was published in the journal Nature Communications allows a fundamental understanding of the electronic properties of this novel semimetal. more
