In a joint research effort, an international team of scientists lead by Emmanuelle Jal (Sorbonne Université) performed a time-resolved experiment at the FERMI free-electron laser to disclose the dynamic behavior of two magnetic element of a compount material in only one snapshot. The X-ray Optics and Applications group developed a dedicated optical element for this experiment that is usable with two different photon energies (colors) simultaneously.
Scientists in the Applied Physics department of Yale University – one of the leading authors, Alexander Grimm, has in the meantime relocated to PSI – have developed a new device that combines the Schrödinger’s cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a quantum computation.
In a joint research effort, an international team of scientists lead by Prof. Giovanni de Ninno (University of Nova Gorica, Elettra Sincrotrone Trieste) now demonstrated that an OAM-dependent dichroic effect can be observed on photoelectrons. The photoelectrons are released from a sample of He atoms that is excited by the strong extreme ultraviolet light pulses from the FERMI free electron laser, whereas the orbtial momentum is imprinted with an intense infrared laser pulse. The X-ray Optics and Applications group of PSI supported the team with their experience in the creation of OAM beams and during the experiments.
In his first paper as lead author, LMN PhD student Adrian Beckert and co-authors demonstrate an algorithm which takes advantage of peak multiplicity to retrieve line shape information. The results were published in Optics Express and are relevant to a wide range of topics, ranging from neutron-scattering to spectroscopy of rare-earth doped solids.
Le PSI participe à des projets de recherche spatiale. C’est ainsi que s’enrichit le savoir sur notre système solaire, mais aussi que se renforce la renommée de la Suisse en tant que développeur fiable d’équipement spatial de pointe.
The Third Edition of "Microlithography: Science and Technology" from Taylor & Francis covers the science and engineering involved in the latest generations of microlithography.
Hexagonal boron nitride (h-BN) “nanomesh”, a two-dimensional insulating monolayer, grown on the (111) surface of rhodium exhibits an intriguing hexagonal corrugation pattern with a lattice constant of 3.2 nm.
La mission Solar Orbiter de l’ESA sera lancée le 10 février. Avec à son bord le télescope suisse à rayons X STIX équipé de détecteurs développés au PSI.
A new PSI spin-off is on the horizon: Dr. Florian Döring, PostDoc in the Laboratory for Micro- and Nanotechnology, received a PSI Founder Fellowship at Park Innovaare.
