The MSc programme Physics offers 5 research-oriented specialisations where you can focus on Theoretical Physics, Quantum Matter and Optics, Biological and Soft Matter, or Cosmology. You can also combine Physics with education, management or science communication.

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

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

Jianfeng Ge and Milan Allen of Leiden University look for majorana quasiparticles using shot noise measurements

The Global Strategy for Plant Conservation, a world-wide effort by the botanist and plant protection community, is making considerable progress in protecting plant diversity around the world, a new report says. The Hortus botanicus Leiden is one of the partners of the project.

This paper, like the seminar on which it is based, considers how the governance of transnational critical information infrastructure (CII) could be approached at the global level. It suggests that when one is thinking about the (potential) governance of CII, it is important to recognise that not all…
