Energiewende

Abkehr von der Kernenergie, Ausbau von Solar- und Windkraft, Energiegewinnung aus Biomasse, Senkung des Energieverbrauchs. Bis 2050 soll die Schweiz klimaneutral werden. Ein ehrgeiziges Ziel, welches durch die zunehmend herausfordernde geopolitische Lage dringlicher denn je geworden ist. Wie lässt sich in den nächsten Jahren eine nachhaltige und widerstandsfähige Energieversorgung für die Schweiz aufbauen? Wie können erneuerbare Energien optimal genutzt werden? Welche neuen Technologien sind besonders vielversprechend? Am PSI suchen Forschende nach Antworten auf diese entscheidenden Fragen.

Workshop crystal growth 2024

Tips and Tricks for the Crystal Growth of Inorganic Materials

We are happy to announce that the call for abstracts for the Workshop on Tips and tricks for the crystal growth of inorganic materials is now open. The workshop brings together experts from the Solid State Chemistry and Condensed Matter Physics communities in order to discuss the accomplished progress and perspectives for future developments in the synthesis and crystal growth of materials with novel and interesting physical properties. The event will take place at the Paul Scherrer Institut (PSI), Switzerland, 26th-27th of August 2024.

Snips of 3D spinwave image

Three-dimensional magnonics

Researchers from an international collaboration between Switzerland, Italy, and Germany have performed the first time-resolved imaging at sub-ns timescales of the three-dimensional propagation dynamics of a spinwave in a synthetic antiferromagnetic nanostructured device, opening up the possibility to investigate magnon dynamics in complex three-dimensional geometries.

Surface oxidation/spin state determines oxygen evolution reaction activity of cobalt-based catalysts in acidic environment

Co-based catalysts are promising candidates to replace Ir/Ru-based oxides for oxygen evolution reaction (OER) catalysis in an acidic environment. However, both the reaction mechanism and the active species under acidic conditions remain unclear. In this study, by combining surface-sensitive soft X-ray absorption spectroscopy characterization with electrochemical analysis, we discover that the acidic OER activity of Co-based catalysts are determined by their surface oxidation/spin state.

All Two-Loop Feynman Integrals for Five-Point One-Mass Scattering

We compute the complete set of two-loop master integrals for the scattering of four massless particles and a massive one. Our results are ready for phenomenological applications, removing a major obstacle to the computation of complete next-to-next-to-leading order QCD corrections to processes such as the production of a H/Z/W boson in association with two jets at the LHC. Furthermore ...

OAM Beam

High-resolution ptychographic imaging at a seeded free-electron laser source using OAM beams

Electromagnetic waves possessing orbital angular momentum (OAM) are powerful tools for applications in optical communications, quantum technologies, and optical tweezers. Now, a consortium of collaborators in France, Italy, Slovenia, Spain, Switzerland, Sweden, and the US reports on using such beams in the extreme ultraviolet region for ptychographic imaging in the cover page article of Optica 11, Issue 3. By controlling the topological charge, the researchers achieve an improvement of 30% in image resolution.

Electron Glass Phase with Resilient Zhang-Rice Singlets in LiCu3O3

LiCu3O3 is an antiferromagnetic mixed valence cuprate where trilayers of edge-sharing Cu(II)O (3d9) are sandwiched in between planes of Cu(I) (3d10) ions, with Li stochastically substituting Cu(II). Angle-resolved photoemission spectroscopy (ARPES) and density functional theory reveal two insulating electronic subsystems that are segregated in spite of sharing common oxygen atoms: a Cu dz2/O pz derived valence band (VB) dispersing on the Cu(I) plane, and a Cu 3dx2−y2/O 2px,y derived Zhang-Rice singlet (ZRS) band dispersing on the Cu(II)O planes.
