Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

Besides physics, the sleep of PhD students also benefits from Vitaly Fedoseev's PhD research. He will receive his doctorate on July 7 for his work on optomechanics within quantum mechanics. And also on a setup that eliminated the need for PhD students to push a button every hour for 72 hours.

The Research in Physics, Quantum Matter and Optics specialisation is an excellent stepping stone for pursuing a PhD degree.

Do you live in Egypt and have you always wondered about all the pharaonic heritage surrounding you? This spring NVIC organizes a beginner’s level, introductory course in Egyptology. In 6 richly illustrated lessons, the history of ancient Egypt will be brought to life, both chronologically as well as…

The Physics and Quantum Matter and Optics specialisation is one of the two programmes Leiden offers in experimental physics. The programme can be tailored to individual needs and interests.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

Historical geo data are gaining in importance. Provided that they are exactly geo referenced, they can be stored into a GIS and thus be combined with all kinds of maps (topographical, pedological, etc.) and datasets. This makes it possible to analyze historical developments in space and time on a detailed…

The programme guarantees a thorough experience on the frontline of physics research with a practical training of communicative and computer skills.

We explore the particle physics and quantum world at the time of the big bang.

Physicists at Leiden University are developing smart chips that can be programmed with light. These chips are more energy-efficient than traditional chips because they do not require a constant power supply. For this research, they will receive funding in the coming years from the Dutch Research Council…

Designing innovative algorithms, thinking outside the box, and brainstorming over coffee with his colleagues — this is what physicist Stefano Polla enjoys most. His success shines through in his nomination for the C.J. Kok Jury Award 2024 for PhD thesis of the Year.

‘Quantum technology is going to change the world, but most people don’t feel connected to it. I want to change that,’ says Julia Cramer, assistant professor at Leiden University. Known for her passion for science communication, Cramer actively seeks opportunities to share the wonders of quantum technology…

Are predictive archaeological maps a reliable tool to play an important role in the spatial planning? One of the goals of this project was to develop best practices for the production and application of the models.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

The specialisation consists of 120 European Credit Transfer System (EC) points and includes mandatory courses and electives (60 EC) and two research projects (60 EC).

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

When you think of physics, do you think only of complicated formulas? You’re not the only one. Therefore, every year, the Leiden Insitute of Physics organises the LION Image Award to show another side of physics: beautiful images about intriguing science.

Is private law ready for the challenges of our time?

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…
