Materials made of self-spinning particles

Matter is either gas, liquid or solid based on how its molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found ...

Metamaterial built from gears

A specifically designed collection of gears is soft on one end and rigid on the other. These robust properties hold even in the event of manufacturing imperfections. This emerging research may lead to new ways of designing ...

Record distance for alternative super-current

Researchers have discovered that electrons that spin synchronously around their axes remain superconductive across large distances within magnetic chrome dioxide. Electric current from these electrons can flip small magnets, ...

First atomic observation of synthetic fuel production

Synthetic fuel is cleaner than natural oil, but its production process is inefficient. Now, for the first time, physicists have directly observed the molecules produced in the chemical process. This paves the way for designing ...

Melting of frozen electrons visualized

For the first time, physicists have visualized the 'melting' of electrons inside a special class of insulators that allows electrons to move freely; the process turns the insulator into a metal and possibly later into a superconductor. ...

Researchers use quantum dots to manipulate light

Leiden physicists have manipulated light with large artificial atoms, so-called quantum dots. Before, this has only been accomplished with actual atoms. It is an important step toward light-based quantum technology. The study ...

MRI machine at the nanoscale breaks world records

A new nuclear magnetic resonance (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 ...

Second layer of information in DNA confirmed

Leiden theoretical physicists have proven that DNA mechanics, in addition to genetic information in DNA, determines who we are. Helmut Schiessel and his group simulated many DNA sequences and found a correlation between mechanical ...

Using colloids to build complex structures

Manufacturers produce high-end technology mostly top-down with large machinery, but small particles can build structures from the bottom up. A major challenge is that these particles easily clump together. Leiden physicist ...

Single molecule detected for use in quantum network

Leiden physicists have detected a single molecule called dibenzoterrylene in a new crystal and found that it is a candidate component for a quantum network. Future quantum computers will need such a network to work together ...
