Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

The future of computing lies in the surprising world of quantum physics, where the rules are much different from the ones ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...

The incredible optical characteristics of textured metal films are prompting physicists to rethink the laws of optics. An international team of physicists led by Henri Lezec and Thomas Ebbesen of ...

In the era of instant data exchange and growing risks of cyberattacks, scientists are seeking secure methods of transmitting ...

Researchers observe metal 3D printing dislocations in real-time - tracking the printing process with X-ray diffraction.
