A couple of years ago, theoretical physicist Carlo Beenakker tracked down the Majorana particles and inspired Leo Kouwenhoven from TU Delft to try to create them in a superconducting nano-structure. He succeeded in doing so in 2012, and the news made headlines around the world. But a lot of work still…

On Thursday 9 November, Leiden University organized its annual Physics Ladies Day for female high school students. To mark this festive day, we put the spotlight on two female researchers, who talk about their experiences in physics.

Using N2 dissociation on Ru(0001) as a representative showcase (for catalysts employed in the Haber-Bosch process), we have shown for the first time that non-adiabatic effects can substantially reduce a molecule’s dissociation probability on a metal surface. These effects are currently completely unaccounted…

Erik de Maaker, Sybille Lammes, Anke Klerkx, and Michiel van Groesen received a 10k€ KIEM grant for 'Networking Heritage at Leiden University' to boost heritage research.

Erik de Maaker wrote a monograph on how Garo, an indigenous community of the extended eastern Himalayas, experience and negotiate such disparities. The book shows how relatedness is reinterpreted as religious practices change, and communally held land ends up being privately controlled. Erik de Maaker…

Making the most vibration-free, cryogenic scanning tunneling microscope in the world. A bold mission, but one that PhD candidate Irene Battisti successfully executed together with the Fine Mechanical Department. The new microscope might shed light on how unconventional superconductivity works. PhD Defence…

Gold nanoparticles give us a better understanding of enzymes and other molecules. Biswajit Pradhan, PhD candidate at the Leiden Institute of Physics, uses gold nanorods to study individual molecules that would be challenging to detect otherwise. Resulting knowledge can be applied to many research fields,…

String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported this week in 'Science'.

The behaviour of strongly correlated electron systems, such as high-temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give physicists a better understanding of the weird behaviour of these kinds of…

We don’t understand how some materials become superconducting at relatively high temperatures. Leiden physicists have now found a surprising connection with auxiliary black holes. It enables us to use our knowledge of black holes on the mystery of high-temperature superconductivity. Publication in Nature…

NWO has assigned Physics Vrije Programma grants to five collaborations of physicists. Leiden University is involved in three of them.

Leiden physicist Milan Allan and his group have discovered an apparent paradox within a material that has zero electrical resistance. They measured trapped charges, while charges should in theory keep flowing in the absence of resistance. The discovery could provide a missing piece of one of the big…

Majorana particles have been getting bad publicity: a claimed discovery in ultracold nanowires had to be retracted. Now Leiden physicists open up a new door to detecting Majoranas in a different experimental system, the Fu-Kane heterostructure, they announce in Physical Review Letters.

The three works present very different aesthetic approaches, crafting dynamic and innovative sound…

Bird, butterfly, fish: when you look through a children’s book, you usually don’t think about the fact that humans divided these animals, depicted in bright colours, into categories. Yet, this division has been discussed for centuries. In her PhD dissertation, Didi van Trijp shows how natural scientists…

The socio-economic effects of climate change often do not receive enough attention. At the EuroScience Open Forum (ESOF) a group of researchers will provide more insight. How does climate change affect whether people work together or conversely end up as opponents? And what can we learn from societies…

An international team of astronomers led by Dutch scientist Martijn Oei has discovered the largest pair of jets from a black hole ever seen.

One of the major stereotypes about Islam is that it is very male-dominant and women-oppressive, but is Islam really that patriarchal? Mahmood Kooriadathodi has been awarded a 250.000 euros Veni grant for his project ‘Matriarchal Islam: Gendering Sharia in the Indian Ocean World’.

Radhika Gupta has received a Consolidator Grant from the European Research Council to study how transnational Islamic charitable networks are entangled with Western humanitarianism and neoliberal welfare frameworks.

Psychologist Omar Burhan discovered in his study of nepotism that the hiring of kin, even if they are competent for the job, makes people feel they are procedurally being treated unfairly. However, certain people are liable to believe that effective leaders transfer their traits to their offspring.…

In Mapping the Pāśupata Landscape: Narrative, Place, and the Śaiva Imaginary in Early Medieval North India, Elizabeth A. Cecil explores the sacred geography of the earliest community of Śiva devotees called the Pāśupatas.

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,…
