Synchronising ultrashort X-ray pulses
Attosecond coherent pulses at SwissFEL will open new experimental possibilities
Kelvin: la scala del freddo
Zero Kelvin: è il punto zero assoluto della temperatura. Poiché il calore è energia, il freddo significa meno energia, ma non può mai esserci energia negativa. Espresso nella scala di temperatura a cui siamo abituati, lo zero Kelvin corrisponde a -273,15 gradi Celsius: niente può essere più freddo di così. Alcuni ricercatori del PSI stanno conducendo esperimenti a bassa temperatura vicino a questo punto zero; altri stanno lavorando su metodi tecnici per abbassare la temperatura nel modo più efficiente possibile.
“La collaborazione è particolarmente importante nella ricerca quantistica”
La ricercatrice del PSI Kirsten Moselund parla delle tecnologie quantistiche, della loro importanza e della situazione attuale in Svizzera. E della sua ricerca nel campo della nanofotonica.

Controlling magnetic waves in a spin liquid
Scientists at the Paul Scherrer Institute PSI have shown that excitation of a spin liquid with intense THz pulses causes spins to appear and align within less than a picosecond. This induced coherent state causes a magnetic field to form inside the material, which is detected using ultrashort X-ray pulses at the X-ray Free Electron Laser SwissFEL.
