A novel concept for extracting information from spectra where traditional post-processing procedures fail, dubbed ‘software-defined spectroscopy’, offers a fresh approach to high-resolution terahertz spectroscopy. The new method implements an ‘optical comb’ and combines it with a programmable modulator, all using components from the optical internet.
PSI congratulates Emmanuelle Charpentier and Jennifer Doudna on winning this year's Nobel Prize in Chemistry. Experiments at the Swiss Light Source SLS in 2013 made it possible to elucidate the structure of the protein complex CRISPR-Cas9.
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.
The PSD is a research partner in the Microsoft Quantum Network, which is a broad community of individuals and organizations collaborating with Microsoft to advance a comprehensive quantum ecosystem, develop practical solutions, and build a robust quantum workforce.
The institutions of scientific excellence are partnering collaboratively with Microsoft to pursue the advancement of quantum computing research, development, and education. The large scale facilities at PSI, in particular the Swiss Light Source, offers unique characterizations techniques to shed light on the secrets of functional materials.
The first endstation at the SwissFEL Athos soft X-ray branch is rapidly developing and on track for first experiments in 2021.
PSI scientists have investigated a material that could be suitable for future data storage applications. They have manipulated the crystalline structure of their sample while measuring how this affects the material’s magnetic and electronic properties.
Analytical Research Infrastructures of Europe (ARIE) join forces to face COVID-19 and other viral and microbial threats
After the joint position paper published as a pre-release in July, in which the Analytical Research Infrastructures of Europe (ARIE) presented their plan to tackle HE Missions, the ARIE enhanced its cross-border, multidisciplinary collaboration to offer Europe a strong and valid weapon against the present COVID-19 challenge and other potential viral and microbial threats.
Long-wavelength pulses from the Swiss X-ray free-electron laser (XFEL) have been used for de novo protein structure determination by native single-wavelength anomalous diffraction (native-SAD) phasing of serial femtosecond crystallography (SFX) data.
We generate frequency-tunable narrow-band intense fields in the terahertz (THz) range by optical rectification of a temporally modulated near-infrared laser pumping a nonlinear organic crystal.
