Laboratory for Micro and Nanotechnology (LMN)
LMN is dedicated to fundamental and applied research with a focus on:
- Outstanding nanoscience by exploiting the synergies between advanced micro/nanofabrication and PSI’s large scale facilities, in particular the Swiss Light Source (SLS)
- Enabling innovations in instrumentation (optics, detectors, diagnostics etc.) for large scale facilities by applying nanotechnology
- Providing advanced micro- and nanofabrication technologies to academic and industrial users, in particular in the area of polymer nanotechnology.
Latest Scientific Highlights and News
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.
Novel optics enable better X-ray Free Electron Laser 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.
