How do quantum materials really respond to light? 🤔
The answer is complex – and a new study from SwissFEL by @au.dk reveals it’s even more so than previously thought.💡

Terbium duet and other quantum art
To create more stable qubits, PSI researchers make terbium ions perform in pairs. Elsewhere, they are using optical tweezers to position atoms with high precision.

PSI researcher Cornelius Hempel performs calculations on quantum phenomena using quanta.⚛️He uses ion traps to effectively slow down time and thus study ultra-fast chemical reactions – e.g. molecules in the retina of the eye.👀

Zeitbremse und Ionenfallen
Cornelius Hempel berechnet Quantenphänomene mit Quanten. Klingt logisch, ist aber hochkomplex. Sein neuester Coup: ein Quantensimulator, der die Zeit verlangsamt.

Detective work for safe syringes 🕵️‍♀️
A team from ANAXAM & PSI has shown that zinc from the needle shield could in rare cases contribute to the clogging of pre-filled syringes. State-of-the-art imaging techniques available at PSI were used to look inside the needle. 💉🔬 #MedTech
Zinc detected in clogged syringes
With the help of researchers at PSI, ANAXAM has been investigating, on behalf of the pharmaceutical company MSD, whether zinc may contribute to clogging of pre-filled syringes.
