Development of a new type of optical receiver, able to restore chaotic signals in free-space optical communication links distorted by atmospheric turbulence. By use of a system of optical antennas integrated into a programmable photonic chip, the receiver can adapt in real time, maintaining the integrity of the signal even in harsh atmospheric conditions. The study by a team of researchers led by Télécom Paris and the Politecnico di Milano, has just been published in Light: Science & Applications, and paves the way for the use of chaos-based encryption for secure, high-speed communication in hostile environments.

A striped charge order has been discovered in the Fu-Kane topological superconductor 2M-WS₂, and its interaction with Majorana bound states (MBS) demonstrates a potential way to manipulate the spatial positions of MBSs.

The largest radio telescope FAST detects 90% circular polarization and rapidly changing linear polarization in the bursts of a fast radio burst (FRB) repeater, imposing new constraint on radiative mechanism of FRBs.
