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.
Our research on multifocus off-axis zone plates was accepted in “Optica”, the highest impact journal of the Optical Society of America. In the paper we report on different ways to combine focusing and beam-splitting functionalities in one single optical element.
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.
PSI takes part in space research projects. This not only expands knowledge about our astronomical home, but also reinforces Switzerland's reputation as a reliable developer of sophisticated space equipment.
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.
On 10 February, the ESA mission Solar Orbiter is scheduled to start. The Swiss X-ray telescope STIX will be launching too – with detectors developed at 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.
