Dr Paolo Crivelli (ETH Zurich, Department of Physics, Institute for Particle Physics and Astrophysics) has recently been awarded an ERC Consolidator grant for his project "Mu-MASS" aiming at a new precision measurement of the Muonium 1S-2S transition energy, ultimately with an improvement by three orders of magnitude.
Eccellenza Professorship to Lea Caminada
Dr Lea Caminada has been awarded a Swiss National Science Foundation (SNF) Eccellenza Professorial Fellowship.
Rendre possible l'impossible
L'utilisation de matériaux multiferroïques devrait ouvrir la voie vers des ordinateurs plus économes en énergie. Avec eux, il suffirait en effet d'un champ électrique pour assurer le stockage magnétique des données. Des chercheurs du PSI viennent de rendre un matériau de ce genre utilisable aux températures de fonctionnement d'un ordinateur.
Marc Janoschek appointed new head of LDM
Dr Marc Janoschek has been appointed new head of the NUM Laboratory for Scientific Developments and Novel Materials LDM. He will take office on November 15, 2018. Marc studied Physics at TU Munich and did his PhD at PSI and TUM on "Neutron Scattering on Chiral Magnets". After that he went to the University of California in San Diego as Feodor-Lynen Fellow. Since 2011 he is head of "Neutron research" in the "Condensed Matter and Magnet Science" group in Los Alamos. For his research Marc has been awarded the Wolfram Prandl Prize and the Los Alamos Fellow Prize for Outstanding Research.

The signing ceremony marks the establishment of a new strategic consortium of European neutron source facilities with the aim, according to the charter, to “facilitate any form of discussion and decision-making process that has the potential to strengthen European neutron science via enhanced collaboration among the facilities”. The founding partners in the consortium include both European and national facilities in France, Germany, Sweden, Hungary, the United Kingdom, Norway and Switzerland. Other qualifying facilities are invited to join at any time.

Le travailleur de force du val Mesolcina
Aldo Antognini a la physique et la convivialité dans le sang. Aldo Antognini, chercheur au PSI, a reçu plus de 2 200 000 francs de l’UE pour sa nouvelle expérience. Son objectif: déterminer la répartition du magnétisme dans le proton. Pour y arriver, ce physicien des particules devra mettre ses talents scientifiques et techniques à contribution, mais aussi son entregent.
Plongée dans un aimant
Pour la première fois, des chercheurs ont réussi à visualiser les directions de l'aimantation dans un objet magnétique tridimensionnel. Les plus petits détails de leur visualisation mesuraient moins d'un dixième de millième de millimètre. Un type de motif exceptionnel est ressorti dans la structure qu'ils ont fait apparaître: des singularités magnétiques appelées points de Bloch, jusque-là connues uniquement en théorie.
