Collapsing energy bands to explore their geometric structure

The geometry and topology of electronic states in solids plays a central role in a wide range of modern condensed-matter systems including graphene or topological insulators. However, experimentally accessing this information ...

Radar with 360° vision

Nowadays it is impossible to imagine industry without robots. Safety laser scanners mostly safeguard dangerous areas and protect people from collisions. But optical sensors have their limitations, for instance when plastic ...

Physicists close in on world's most sensitive resonators

In their quest to make the world's most precise sensors, Cornell physicists have developed a novel method of manipulating mechanical resonators to be sensitive enough to work at the quantum scale.

Beating cyber criminals with quantum solutions

As hackers get more sophisticated in their cyber crime efforts, we need to look to new technology to make our systems more secure, and potentially unhackable.

Top-precision optical atomic clock starts ticking

A state-of-the-art optical atomic clock, collaboratively developed by scientists from the University of Warsaw, Jagiellonian University, and Nicolaus Copernicus University, is now "ticking away" at the National Laboratory ...

Controlling light on a chip at the single-photon level

Integrating optics and electronics into systems such as fiber-optic data links has revolutionized how we transmit information. A second revolution awaits as researchers seek to develop chips in which individual atoms control ...
