As a lawyer, how can you contribute to ensuring that the best interests of the child play a greater role in immigration law? That question was the topic of asylum lawyer Bart Toemen's guest lecture in the course ‘Kind en migratie’ (child and migration), given in the master’s programme ‘Jeugdrecht’ (Child…

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

Leiden students often prefer complicated theory and a difficult test to experiments. Yet associate professor Paul Logman believes students learn a lot from practical teaching. He challenges his students to come up with their research questions themselves. The Leiden Institute of Physics (LION) is at…

In this article, Jasmijn Boeken, explores in which ways the defining characteristics of the different zones can be found in the digital sphere.

Measurements on a superconducting material show an abrupt transition between a normal metal and a 'strange' metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. 'We don't have any theoretical machinery for this', says theoretical physicist Jan Zaanen,…
