For many system in statistical physics the microcanonical and canonical ensemble are equivalent in the thermodynamic limit, but not for all.

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

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.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Om de officiële start van de Leiden Chinese Queer Collection (LCQC, 莱顿华语酷儿文献收藏) te vieren, om wetenschappelijk onderzoek in Chinese queer studies te bevorderen en om de zichtbaarheid van Chinese queergeschiedenis en -cultuur te vergroten, organiseert de LCQC-stuurgroep op 24–25 juli 2025 een tweedaagse…

We describe certain birational modifications of nodal relative curves over a regular base of arbitrary dimension.

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

This Thesis shows discoveries in non-linear astrochemical kinetics as well as a deeper analysis of dark clouds chemistry.

Moritz Jesse has been awarded a Jean Monnet Chair by the European Commission. In his MIND-EU Project he will focus on a coherent way to teach Migration, Integration, and Non-Discrimination at Leiden Law School at bachelor and master level.

There are study programmes at LIACS that offer the opportunity to do an internship or research project, as part of the curriculum.

Leiden University’s Academic Challenge

'Onderschat nooit de verbindende kracht van wetenschappelijk onderzoek en onderwijs.' Dat stelde rector magnificus Carel Stolker in zijn toespraak op de dies, waarbij hij vooral doelde op de naderende Brexit. Een boodschap die veel weerklank vond in de (internationale) media.

Een jaar geleden kreeg universitair docent Paz Gonzalez een Comeniusbeurs om een wetenschappelijk tijdschrift voor en door studenten op te zetten. Nu is het eerste dubbeldikke nummer van The New Scholar een feit. ‘We willen de diversiteit van de faculteit laten zien.’

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

Hanne Cuyckens en Daan Weggemans zijn per 1 september 2023 benoemd tot Teaching Fellow en lid van de Leiden Teachers’ Academy (LTA).

Today, knowledge is the most crucial element to stimulate organizational competitiveness and economic development.

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

This thesis describes how different colours of light affect various aspects of the growth and development of Arabidopsis and tomato plants⁠.

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.
