Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

From punch card-operated looms in the 1800s to modern cellphones, if an object has an "on" and an "off" state, it can be used ...

The research paper reports a breakthrough that will enable gravitational-wave detectors to reach extreme laser powers. It ...

Quantum sensors can be significantly more precise than conventional sensors and are used for Earth observation, navigation, ...

As quantum computers threaten traditional encryption, researchers are developing quantum networks to enable ultra-secure communication. Scientists at Leibniz University Hannover have pioneered a new ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This phenomenon is ...
