World-class research is integral part of the master’s education. You obtain a Physics degree from an institute with an international reputation. Research in this programme is fundamental and curiosity-driven.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…

The Physics and SCS master specialisation gives you the opportunity to combine Physics research with different aspects of science communication.

LION offers a PhD program in which candidates carry out independent research on a specific topic, culminating in a PhD thesis.

The Physics and Education master specialisation gives you the opportunity to combine physics research with an excellent education in becoming a physics teacher.

The programme will give you the opportunity to choose from a broad range of topics to study. You will be part of an international multidisciplinary research team at the LION.

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

An overview of awards and prizes granted to our staff and students in 2020, as well as special appointments at Leiden University and other institutions.

The programme offers you the ability to combine experimental research with theoretical courses. The programme helps you grow into an independent and skilled physicist.

Cambridge University Press has published a new book co-authored by researchers from Leiden University, offering both an introduction to machine learning and deep neural networks, and an overview of their applications in quantum physics and chemistry — from reinforcement learning for controlling quantum…

PhD candidates carry out a programme of independent research and additional (limited) course work, culminating in production of a PhD thesis in typically 4 years.

This thesis described the development of novel scanning tunneling microscopy techniques to investigate strongly correlated electronic states in quantum matter.

Quantum critical metals at vanishing fermion flavor number.

An online course to teach our international students their first words in Dutch, American presidents in Leiden and how Neanderthals made the very first glue: view a selection of our most read English news in the past year.

The red carpet treatment of expats, terrorism studies and women professors who took over the Senate Chamber. These are the best read articles of 2018.

The Leiden University Green Office is pleased to announce the details of its Spring Event, which will consist of a poetry reading and a clotheswap!

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

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

In my thesis I study Majorana fermions from three different perspectives. The first one corresponds to non-interacting Majorana fermions that, however, pose non-trivial topological properties. The second one corresponds to strongly interacting Majoranas and the third to relic neutrinos. No one knows…

In the thesis we demonstrated an 85% state transfer efficiency between two mechanical modes coupled to a common optical mode via stimulated Raman adiabatic passage (STIRAP) in the classical regime. We also showed possibilities to manipulate quantum states of the mechanical modes via STIRAP.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Visualising structures of life

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

In this thesis, we examine various systems through the lens of several numerical methods.

The dissertation describes TEM experiments on heterogeneous catalysts.

How can we develop a new microscope that can distinguish individual atoms in proteins?

In this study an attempt has been made to describe the degree in which the new objectives of the school subjects Greek and Latin, as formulated at the theoretical level by institutes as curriculum planning committees, are are incorporated by the teachers in their actual teaching practice.

Teaching reading comprehension in secondary education

This thesis consists of two subjects, that are both a consequence of radiation pressure.

Skandapurāṇa IV presents a critical edition of Adhyāyas 70-95 from the Skandapurāṇa , with an introduction and annotated English synopsis.

Mechanical interactions between cells and their environment play an important role in many biological processes.

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

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

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

In this thesis, classes of strongly interacting quantum field theories, have been studied.

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.

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…

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…
