Magnetic imaging of spin waves and magnetic phase transitions with nitrogen-vacancy centers in diamond
The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

Conspiracy thinking and social media use are associated with ability to detect deepfakes
Deepfakes zijn video’s die gemanipuleerd zijn om twee personen te verwisselen. Ze kunnen moeilijk te onderscheiden zijn van de originele video’s. In onze studie laten we zien dat mensen die meer complotdenken en mensen die meer gebruikmaken van social media beter zijn in het herkennen van deepfakes.

Conflicts between migrants and locals in Leiden and Rotterdam, 1680-1800
Due to its economic prosperity, its policy of (relative) religious tolerance, and its large numbers of migrants, the Dutch Republic has long had a reputation of being the prime example of ‘tolerance’, especially during the seventeenth century. Although the great variety of newcomers in the Dutch Republic…

luminescence of gold nanorods: applications to single-particle tracking and spectroscopy
Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.
