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).

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

As an alternative to the diving board shaped force sensor, we are now developing a magnetically levitated small superconducting particle – or ‘Lead Zeppelin'' – as our mechanical resonator. We explore routes towards detection of gravity between small objects.

By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.  

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

A lot of our research is performed at temperatures close to absolute zero, among other reasons because this increases the sensitivity of the measurements. 

How can we ensure a more resilient and sustainable supply of Rare Earths in the EU in the future?

Kaveh Lahabi's lab explores the exotic physics of quantum materials, whose underlying physics seems to have more in common with elementary particles and black holes, than ordinary metals and semiconductors.

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

Astronomer Alexander Mushtukov, currently working at the University of Amsterdam, received a Veni grant of 250,000 euro’s which he will execute in Leiden. Supervised by Simon Portegies Zwart, Mushtukov will use advanced simulations to understand the unknown physics in extremely bright neutron stars.

A 90+ seat room in the LUMC Main Building. Rolling, flexible, tables on a carpetted floor allows for the quiet re-arrangement of the room to support teaching in groups of many size. Nearly 3 full walls are covered in magnetized, writable surfaces, and there are hinged TVs on the walls which can be beamed…

X-Ray Diffraction (XRD), Nuclear Magnetic Resonance (NMR) and Cryo-electron microscopy (Cryo-EM) are the three main methods for solving structures of macromolecules.

Can a proposed new radiofrequency approach to graphene biosensors lead to groundbreaking changes in genome mapping?
