The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

Dynamic nuclear polarization with paramagnetic agents can enhance nuclear magnetic resonance signals by orders of magnitude. The mechanism of enhancement depends a.o. on the magnetic resonance properties of the agents used. Electron spin relaxation times at NMR relevant magnetic field/microwave frequencies,…

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.

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.

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).

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

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).

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

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.  

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

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

The Cryogenics Department has a liquid helium production unit and an automatic liquid nitrogen filling plant.

My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

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.

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

This thesis describes how to scale down concepts of macroscopic mechanical metamaterials to the thermal scale using a system of flexibly-linked colloids.

Het is een wijdverbreid idee dat (post-)middeleeuwse steden een sterfteoverschot hadden en zij slechts in leven konden blijven door de toestroom van migranten; een fenomeen dat bekend staat als het ‘urban graveyard’-effect. Over details valt te twisten, maar duidelijk is dat de stad en de dood dichter…

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.

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

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…

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine. The available expertise extends…
