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.

Hidden magnetism uncovered in a charge ordered bilayer kagome material ScV6Sn6

Charge ordered kagome lattices have been demonstrated to be intriguing platforms for studying the intertwining of topology, correlation, and magnetism. The recently discovered charge ordered kagome material ScV6Sn6 does not feature a magnetic groundstate or excitations, thus it is often regarded as a conventional paramagnet. Here, using advanced muon-spin rotation spectroscopy, we uncover an unexpected hidden magnetism of the charge order. We observe an enhancement ...

Kondo screening in a Majorana metal

Kondo impurities provide a nontrivial probe to unravel the character of the excitations of a quantum spin liquid. In the S = 1/2 Kitaev model on the honeycomb lattice, Kondo impurities embedded in the spin-liquid host can be screened by itinerant Majorana fermions via gauge-flux binding. Here, we report experimental signatures of metallic-like Kondo screening at intermediate temperatures in the Kitaev honeycomb material α-RuCl3 with dilute Cr3+ (S = 3/2) impurities.

Sustainable Group-IV Active Photonics Research Sinergia Project granted

We are excited to announce that our joint Sinergia Project: Sustainable Group-IV Active Photonics Research (SUGAR) has been approved for funding by the SNSF and will start in the spring of 2024. SUGAR is an interdisciplinary project that aims to develop a more sustainable photonics platform, based on group IV elements (Si, Ge, Sn). The proposal emphasizes sustainability throughout the entire device life-cycle, incorporating life cycle assessment (LCA) from extraction to end-of-life.

SNSF funds new LNS projects on quantum materials for 1.75 million

Scientists working on exotic magnetism at the Laboratory for Neutron Scattering and Imaging (LNS) are to receive two project fundings from the Swiss National Science Foundation (SNSF), amounting to 1.75 million Swiss francs.

A more efficient degrader for proton therapy

At PSI’s Center for Proton Therapy (CPT), protons are used to treat cancerous tumours in a highly targeted way that spares healthy tissue as much as possible. This is the result of the characteristic way in which charged particles interact with matter, so that a beam of protons deposits most of its energy at a certain depth in a material depending on the energy and the composition of the material. The dedicated medical cyclotron COMET accelerates protons to an energy of 250 MeV, which then have to be "slowed down" so that the energy matches the depth of the tumour to be treated.

New Study Reveals Surprising Climate Benefits of Agriculture

The big challenges our planet faces—like climate change, food supply, water, and biodiversity—are all interlinked. While agriculture continues to be the primary source of food for human kind, it imposes climate challenges especially through emissions like greenhouse gases and ammonia. To solve this, we need a new approach that reduces the harmful effects of farming on the climate.
