Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

Topological photonics promises robust light transport immune to disorder, but existing linear systems are essentially static ...

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference ...

Researchers observed 2D melting in real time by tracking skyrmions, revealing how ordered magnetic lattices become disordered at the microscopic level. (Nanowerk News) What occurs during the melting ...

A proposed experiment that would involve trapping atoms on a two-layered laser grid could be used to study the mechanism behind high-temperature superconductivity. Developed by physicists in Germany ...

Snapshots of the skyrmion lattice during the melting: an ordered skyrmion lattice on the left while the lattice structure has vanished on the right. What occurs during the melting process in ...
