Truth is stranger than fiction. In 1997 Juan Maldaceña discovered a remarkable dictionary that translates equation for equation the physics of black holes in string theory into the more conventional physics of quantum mechanics of interacting particles. The remarkable possibility exists that…

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Can we make quantum devices from quantum surprises? And can we explore and build life from the nanoscale up?

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

Heritage protection is increasingly understood by nations and other actors as playing a critical intersectoral role in supporting wider development and diplomacy outcomes through soft power and cultural relations.

Maria Yazdanbakhsh, Professor of Parasitology at the Leiden University Medical Centre (LUMC), has been awarded an ERC Advanced Grant of 2.5 million euros. She will investigate why people in Africa and Southeast Asia respond less to certain vaccines than Europeans. Her goal is to find a solution for…

Researchers from the Institute of Environmental Sciences (CML) identified six top priorities where environmental interventions can make the most difference. By doing so, they hope to help researchers and policymakers make the most out of the limited, available resources to protect people and the pla…

A significant percentage of children who have spent a period in youth care institutions or foster homes since 1945 received inadequate protection from physical, psychological and sexual violence. Interventions by supervisory authorities in cases involving violence were inadequate.

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the emerging field of quantum acoustics.

The Geneva Conventions and customary international humanitarian law clearly prohibit any attacks on medical units and establishments during armed conflicts. Unfortunately, despite this clear prohibition, medical personnel and medical facilities continue to be the subject of attacks. Doctors now risk…

Investigations conducted by several Dutch child protection bodies within family situations are inadequate. Due to lack of knowledge, time and money, these investigations are not carried out properly, with major consequences for the families involved.

The project has been done in the Quantum Matter Optics group under the supervision of Dr. Wolfgang Löffler and Prof.dr. Carlo Beenakker. The title of the presentation is:

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…
