There are miniaturisation beams, microrobots, and ice skaters who suddenly drop into a hole in the ice. Students of the local MBO Rijnland let their imagination run free while animating Leiden physics research. The result is eleven surprising and very diverse science animations.

A new discovery proves that it matters which approach researchers take in analyzing large physical, social or biological systems that have a networked structure. Ever since the early 1900s, scientists have assumed each approach is equivalent. Now many results in statistical physics may no longer hold.…

The Nobel Prize in Physics 2016 goes to David Thouless, Michael Kosterlitz and Duncan Haldane for theoretical discoveries in the field of topological materials. Haldane spent part of 2008 in Leiden; he is the 14th Lorentz Professor to win a Nobel Prize.

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

This year, two Leiden physicists have earned a prestigious ERC Starting Grant. With a budget of 1.5 million euros, this is one of the largest individual grants for scientists.

An ICE agent fatally shot Renee Good in Minneapolis on 7 January, igniting nationwide fury over escalating federal violence. Could such an incident occur in the Netherlands?

At the winter conference of the Dutch Christian student union CSFR, Mark Dechesne, Associate Professor, spoke about the decline in terrorist violence in the Netherlands.

Research has shown that terrorist attacks in the US are more often committed by right-wing extremists than by islamitic extremists. However, news about attacks by right-wing extremists hardly ever reach the media. Jelle van Buuren tells the Dutch newspaper Trouw that right-wing extremists are at least…

Citizens in multiple crime-ridden countries strongly support the militarization of security—that is, placing the military in charge of traditional policing duties. Yet, we know little about the determinants of such support. Do people approve of militarization even in the face of human fatalities? Political…

New research has revealed that one of Europe’s largest prehistoric mass graves records the deliberate killing of women and children, showing how gender- and age-selective violence was used to disrupt communities and assert power in the Early Iron Age. Leiden archaeologist Jason Laffoon was involved…

As of 1 June, Leiden University has appointed Sense Jan van der Molen as Professor Physics of Condensed matter. He investigates the unique electronic properties that arise when atomic thin layers are stacked on top of each other into new materials.

In this thesis, we show how MRFM can usefully contribute to the field of condensed-matter.

The bachelor education programmes of Physics and Astronomy in Leiden combined have the highest percentage female first year students in The Netherlands, according to numbers published by the Dutch Journal of Physics.

Wim van Saarloos will become vice president of the Royal Netherlands Academy of Arts and Sciences (KNAW), and return to the Leiden Institute of Physics as professor of theoretical physics. Currently, Van Saarloos is Transition Director at the Netherlands Organisation for Scientific Research (NWO).

Researchers from five different discplines work together in this interdisciplinary initiative.
