Twisting light to enable high-capacity data transmission

For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used ...

Supercurrents gone chiral: new type of superconducting junction

Unconventional superconductors form one of the big mysteries in physics. Among them is strontium ruthenate, which stands out as a controversial superconductor. During his Ph.D., Leiden physicist Kaveh Lahabi has provided ...

Chemical bond versus electromagnetic waves

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the ...

Tiny bubbles of bacterial mischief

Margarethe (Meta) Kuehn studies vesicles—little bubbles that bud off bacterial membranes. All sorts of things may be tightly packed into these bubbles: viruses, antigens, and information a bacterium will need to make cells ...
