Two-color snapshots of ultrafast charge and spin dynamics
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 develop a new kind of qubit based on the concept of Schrödinger’s cat
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.
Photoelectric Effect with a Twist
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.
Efficient analysis method for multiplet lines in Fourier space
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.
Zur Sonne und noch viel weiter
Das PSI beteiligt sich an Projekten der Weltraumforschung. Damit erweitert sich nicht nur das Wissen über unsere astronomische Heimat, sondern festigt sich auch das Renommee der Schweiz als zuverlässiger Entwickler von anspruchsvollem Weltraumequipment.
Microlithography: Science and Technology
The Third Edition of "Microlithography: Science and Technology" from Taylor & Francis covers the science and engineering involved in the latest generations of microlithography.
2D Materials
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.
Schweizer Röntgen-Teleskop STIX bricht zur Sonne auf
Am 10. Februar soll die ESA-Mission «Solar Orbiter» starten. Mit dabei ist auch das Schweizer Röntgen-Teleskop STIX – mit Detektoren entwickelt am PSI.
Florian Döring received the PSI Founder Fellowship
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.
