Kidney failure is a serious issue because kidneys cannot regenerate themselves after injury. A possible solution consists of artificially growing healthy kidney tissue. To achieve that, scientists first need to understand kidney development during the earliest stages, in the fetus. Leiden researchers…

Professor Renata Kallosh (Stanford University), one of the world’s leading theoretical physicists, will be this summer’s Lorentz Professor at the Leiden institute for theoretical physics. Her main areas of interest are cosmology and string theory. She studied physics in Moscow, where she also obtained…

Scientists need individual photons for quantum cryptography and quantum computers. Leiden physicists have now experimentally demonstrated a new production method. Publication in Physical Review Letters on July 23rd.

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.…

A new NMR microscope gives researchers an improved instrument to study fundamental physical processes. It also offers new possibilities for medical science, for example to better study proteins in Alzheimer patients’ brains. Publication in Physical Review Applied.

Neurological diseases, such as Alzheimer's disease, are characterised by aggregates of protein in the brain. The connection of these aggregates to the disease itself is unclear. Martina Huber, Enrico Zurlo and colleagues published a new method to monitor the formation of these aggregates.

Jaap Kautz and Johannes Jobst have won the NeVac prize for developing a completely new method for studying electrical conductivity. The article they and their team leader Sense Jan van der Molen wrote about this subject was praised by the jury for its clarity. The prize will be presented to them on…

Physicist Martin van Hecke receives a 2.5 million euro ERC research grant for research into information processing materials. Starting out with a piece of rubber that can count to ten.

Goldband, Skrillex, Róisín Murphy and... quantum: the latter may not be a band but is part of the Lowlands line-up nonetheless. Scientists from Leiden University are using the festival for research on the very smallest particles.

Optical detection of a single electron using a single molecule has never been done. Leiden physicist Michel Orrit and his team have now identified a molecule that is sensitive enough to detect an electron at a distance of hundreds of nanometers. The results are published as a cover article in ChemPh…

Leiden emeritus professor George Miley receives an honorary doctorate from Trinity College Dublin on 8 December. ‘I never dreamed that I would receive an honorary doctorate somewhere, and this is all the more emotional because it's in the city where I spent the first 21 years of my life.’

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.

How can a single origami crease pattern be folded into two precisely defined target shapes? Researchers at AMOLF and Leiden University have created an ‘alphabet’ of 140 origami ‘puzzle pieces’ that allows them to do just that, as described today in Nature Physics. This discovery could help in the construction…

Koen Bastiaans and his colleagues discovered a new quantum liquid unlike anything ever seen. They did it by using a technique that can be compared to listening to the sound of raindrops falling on a roof. Publication in Science 29 October.

Leiden physicists have created a light source that emits individual particles in an identical state through optical fibers. Using this setup, their measurements can last longer and are more efficient, meaning they can perform more in-depth research on bizarre quantum effects, such as interference and…

Leiden physicists and chemists have managed to bring two graphene layers so close together that an electric current spontaneously jumps across. In the future this could enable scientists to study the edges of graphene and use them for sequencing DNA with a precision beyond existing technologies. Publication…

Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Leiden physicists have now found that the charging process of ionic liquids purely depends on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential.…

The more complex the object, the harder it is to fold up. Space satellites often need many small motors to fold up an instrument, and people have difficulty simply folding up a roadmap. Physicists from Leiden and Amsterdam have now designed a structure that folds itself up in several steps. Publication…

Water droplets float in a hot pan because of the so-called Leidenfrost effect. Now physicists have discovered a variation: the Elastic Leidenfrost effect. It explains why hydrogel balls jump around on a hot plate making high pitched sounds. Publication in Nature Physics on July 24.

Stars orbit black holes while jumping up and down. This is the prediction of a theoretical model developed by Leiden physicist Satish Kumar Saravanan, based on Einstein’s theory of relativity. He defends his PhD thesis on July 7th.

Are Weyl particles the ideal conductors? Do cells without a cell wall play a role in chronic Tuberculosis infections? Carlo Beenakker and Dennis Claessen want to answer these questions. They both received a KLEIN grant from the NWO. With these grants, NWO wants to stimulate innovative, fundamental r…

From lectures by Robbert Dijkgraaf to a telescope on the ocean floor: during his double bachelor’s in Physics and Astronomy, Jelle Oonk discovered that the path to big cosmic answers sometimes runs through the smallest, hardest-to-catch particles—neutrinos.

To understand how the brain works, it is essential to map it out in detail. This appears to be possible with a microscopy technique in which Leiden physicists excel. This breakthrough could significantly advance the human quest to understand brain functions.

Quantum games aren’t just a fun way to explain quantum physics — they may also unlock new discoveries. According to physicist Evert van Nieuwenburg, these games create structure and clear rules. Simply playing them can even contribute to better quantum software.

Science journalist Anna Gimbrère and physicist Julia Cramer will open the Quantum Escape Room in Eindhoven on Wednesday, 17th of December. Researchers from Leiden worked closely with the designers to make sure the escape room is not only exciting, but also truly quantum.

Photonics, quantum research and semiconductor technology: Leiden University welcomed a high-level international delegation from Taiwan, to explore new opportunities for working together on innovations for future photonic quantum computers.

They are only a few tens of micrometres long — far smaller than the width of a human hair – yet these robots can swim, sense, navigate and adapt in ways that look surprisingly life-like. And all this without having a brain.

Soft structures that can take on different shapes without any external drive. Leiden physicists Daniela Kraft and Julio Melio created them in their lab. They present their groundbreaking research on microscale metamaterials in Nature - a breakthrough that opens the door to smart, reconfigurable materials…
