We explore the possibilities to combine magnetic resonance techniques with atomic force microscopy together in a single microscope: the MRI-AFM, also called Magnetic Resonance Force Microscopy (MRFM).

With each discovery that is made, the universe reveals a fraction of its secrets: the most distant galaxies and quasars, the atmosphere of exoplanets, evidence of dark matter, complex molecules in space. This is what fills the days and nights of the researchers from the Leiden Observatory and their…

How do you make a technology sustainable that does not even exist yet? Well, by bringing together an interdisciplinary team of pioneering European experts right at the start and paying attention to sustainability right from the development phase.

Lyndsey Housden teaches in the Interactive/Media/Design department at the Royal Academy of Art (KABK), The Hague. She is a researcher and artist, working with interactive and haptic installations, spatial design and interdisciplinary projects for exhibitions, theatre, and festivals.

With a pioneering project like the quantum computer, it’s a good idea not to place all your bets on a single horse. In Leiden’s Quantum Optics research group, instead of working on a Majorana-based qubit, people are working on a qubit based on an ‘artificial atom’. If that becomes the basis of the quantum…

The master’s programme Physics at Leiden University offers a wide range of specialisations from theoretical research to cosmology. You will be trained for a career in research or for a more practical-oriented specialisation. The programme offers a wide choice of individual study paths that take into…

The 2018 Physics Nobel Prize is awarded to Arthur Ashkin, Donna Strickland and Gérard Mourou for their research on optical tweezers based on lasers. Leiden physicists comment in the following media.

Biophysicist Rolf Harkes has developed a microscope to optically localize individual molecules in living cells. It improves monitoring of diseases like cancer and Parkinson’s at the cellular level. Defende PhD thesis on t13 January 2016.

On September 12, Michel Orrit received his Spinoza prize in the Royal Theatre in The Hague from OCW Secretary of State Sander Dekker. With the award comes a budget of 2.5 million euro, to be spent freely on scientific research, and the coveted Spinoza statue. Orrit shared the honor with Eveline Crone…

Astronomers Professor Christoph Keller and Dr Frans Snik will be developing a commercial module for measuring fine particulates. They have been awarded an STW Demonstrator subsidy of 138,000 euros.

The METIS instrument that’s being built for ESO's future Extremely Large Telescope (ELT) in Northern Chile under the leadership of the Dutch Research School for Astronomy (NOVA) has reached an important milestone: the preliminary design has been approved.
