Manipulating electron spin using artificial molecular motors

Artificial molecular switches and machines have undergone rapid advances over the past several decades. Particularly, artificial molecular motors are highly attractive from the viewpoint of chirality switching during rotational ...

A microlaser emitting helical light

Researchers recently demonstrated the realization of an integrated microlaser based on a novel design that emits light in chiral modes, thus producing corkscrews of light. An object is said to be chiral if it can be distinguished ...

The taming of the light screw

DESY and MPSD scientists have created high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might ...

Dung beetles navigate better under a full moon

Of all nocturnal animals, only dung beetles can hold their course using polarized moonlight. Researchers at Lund University in Sweden have now shown that beetles can use polarized light when its signal strength is weak, which ...

Excitons pave the way to higher-performance electronics

After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.
