Fondements de la nature

A l’Institut Paul Scherrer, les scientifiques cherchent des réponses à la question essentielle des structures élémentaires de la matière et des principes fondamentaux de fonctionnement dans la nature. Ils étudient la structure et les propriétés des particules élémentaires – les plus petits composants de la matière – ou se penchent sur la question de savoir comment les molécules biologiques sont structurées et remplissent leur fonction. Les connaissances qu’ils acquièrent de la sorte ouvrent de nouvelles pistes de solution en sciences, en médecine ou dans le domaine des technologies.

Move the soft mode by electric fields in quantum paraelectric SrTiO3

PSI Researcher used inelastic neutron scattering to show how collective lattice vibrations can be controlled by electric fields. These results indicate that different eigenmodes can couple in field in this incipient ferroelectric.

Conventional superconductivity in the doped kagome superconductor Cs(V0.86Ta0.14)3Sb5 from vortex lattice studies

A hallmark of unconventional superconductors is a complex electronic phase diagram where intertwined orders of charge-spin-lattice degrees of freedom compete and coexist. While the kagome metals such as CsV3Sb5 also exhibit complex behavior, involving coexisting charge density wave order and superconductivity, much is unclear about the microscopic origin of the superconducting pairing. We study the vortex lattice in the superconducting state of Cs(V0.86Ta0.14)3Sb5, where the Ta-doping suppresses charge order and enhances superconductivity. Using small-angle neutron scattering ...

Fourth Mu3e Data Challenge

Fourth Data Challenge

The Mu3e data challenges aim at establishing the data processing and storage procedures as well as the online monitoring tools. To this end, we use simulated data to test all involved systems and further develop the code. In the forth edition, we aimed at incorporating the farm FPGAs, GPU selection and advanced subdetector monitoring tools.
