The explanation from physicist Scott Waitukaitis for the screaming and bouncing gel balls in a hot pan has been covered in several media, including the Washington Post.

On an apparently normal cube a pattern of hollows and bulges appears when the cube is compressed. A method has been developed to design such three-dimensional structures and to construct these using simple building blocks. Publication in Nature.

Manufacturers produce high-end technology mostly top-down with large machinery, but small particles are able to build structures by themselves from the bottom up. A major challenge is that these particles easily clump together. Leiden physicist Daniela Kraft has developed a method to use this phenomenon…

Mimicking photosynthesis to produce bioplastics sustainably and efficiently. Researchers from the Institute of Biology Leiden (IBL) and the Leiden Institute of Chemistry (LIC) will assess this new approach. ‘An exciting opportunity to explore a new, appealing research topic in a collaboration between…

Salt crystals, a nano-sized golf stick and molten glass. The LION Image Award competition of 2023 yielded a lot of beautiful images once again. But in the end, only one can be the winner.

Leiden physicists Alexandre Morin and Samadarshi Maity study self-organisation and flocking phenomena. They shed light on flocking, which helps to understand how it is possible that birds in a flock don't collide. With plastic microbeads, they create an experimental setup and they developed a mathematical…

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.

Leiden alumnus and writer Tomas Lieske has published a novel which is set in the house of Paul Ehrenfest. Ehrenfest was a famous physicist who organized round table events every Wednesday evening at his home in Leiden in the early twentieth century. The big names from modern physics frequented these…

Tonight 20:25, Julia Cramer, expert in quantum information and communication science, is a guest in the television science programma Atlas

The European Research Commission (ERC) has awarded Advanced Grants to two Leiden researchers. Joke Meijer will be researching the effect of the biological clock on our health and Carlo Beenakker will be looking for Majorana fermions in superconductors.

The Leiden Institute of Physics has been awarded three out of twelve available grants from the FOM Projectruimte. Principal Investigators Milan Allan, Stefan Semrau and Carlo Beenakker all receive around 400,000 euro for their research.

This doctoral project by artist and educator Luiz Zanotello engenders a postcolonial understanding of time, space and movement by means of artistic research methods. The project examines the contradictory effects of the abyssal line of thought within the tropics as a starting point.

Lecture, Tuesday Talks: Science Insights

Scientists have developed a material that breaks one of the fundamental principles governing many physical systems. Ordinary materials transmit external forces equally, no matter where the pressure comes from. The newly developed material breaks this rule and could potentially be of interest in soft-robotics…

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…

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.
