Femtosecond laser writing is a transformative technique that utilises ultrashort laser pulses to locally modify the refractive index of a material, enabling the fabrication of intricate ...

Researchers have pushed the limits of the possible in the field of atomic-scale spin-optics, creating a spin-optical laser from monolayer-integrated spin-valley microcavities without requiring ...

A compact optical lattice clock with a volume of 250 liters has been developed. The system includes a physics package for conducting spectroscopy on the clock transition within a vacuum chamber, ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

This hybrid platform enables a new class of experiments—ones that could finally let us test whether gravity needs to be described by quantum theory." The new paper demonstrates laser cooling of a ...

Developers used shallow “web” of laser light to trap atoms, instead of previous optical lattice. The red dot is a reflection of the laser light used to create the atom trap. Enabling pinpoint ...

Trapped and squeezed: A single nanoparticle made of glass (a white point near the centre of the photo) is confined in an optical potential created with a focused laser beam. By detecting the light ...

Not all magnets are the same. When we think of magnetism, we often think of magnets that stick to a refrigerator’s door. For these types of magnets, the electronic interactions that give rise to ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.
