We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

Although it is often assumed that the stereochemistry in Ugi multicomponent reactions is determined in the final Mumm rearrangement step, experimental and computational evidence that Ugi reactions on hydroxylated pyrrolines proceed under kinetic control is reported.

Unconventional superconductors form one of the big mysteries in physics. Among them is strontium ruthenate, which stands out as a controversial superconductor. During his PhD, Leiden physicist Kaveh Lahabi has provided new insights into the nature of superconductivity in this material, leading to a…

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.

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

Curved single crystals provide variable, but well-defined surface structures.

The Biomedical Microscale Analytics group is led by Dr. Rawi Ramautar. In present-day metabolomics, and bioanalysis in general, the analytical toolbox used encounters difficulties for the analysis of limited amounts of biological samples. As a result, a significant number of crucial biomedical/clinical…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

The research in my group addresses a range of topics related to quantum many-body physics.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

In our lab, we investigate the physics and material properties of low-dimensional systems.

How does the extracellular matrix coordinate endothelial cell behavior during angiogenesis, and how do metabolic waste-products and matrix-degrading enzymes produced by the tumour modify the extracellular matrix so as the change the cellular coordination?

The Dick Stufkens Prize 2020 for the best PhD thesis of the Holland Research School of Molecular Chemistry has been awarded to Dr Mark Koenis. Koenis graduated 21 February with the distinction cum laude on his thesis 'Advanced Spectra Analysis to Determine Complex Structure and Chirality'. He describes…

The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

In the field of metabolomics, capillary electrophoresis-mass spectrometry (CE-MS) has become a very useful analytical technique for the profiling of highly polar and charged metabolites in biological samples. In order to highlight the unique features of CE-MS for metabolomics studies, Dr. Rawi Ramautar…

NWO has assigned Physics Vrije Programma grants to five collaborations of physicists. Leiden University is involved in three of them.

Researchers at Leiden University and TU Delft have combined two techniques that are used to measure the structure of biomolecules, creating a method that is ten times more sensitive.

Theoretical physicists research a special class of particles; Weyl fermions. They have found them to exhibit paradoxical behavior, in contradiction to a thirty-year old fundamental theory in electromagnetism. A possible application is a new kind of electronics—spintronics.
