Abstract: Contribution: There are many on-line resources available to learn about optics and photonics, but no assessment tools exist to evaluate the learning achievements. This paper presents an ...

Antiferromagnetic materials, with antiparallel atomic spins and zero net magnetization, are fast and resistant to external magnetic interference, making them ideal for high-speed, high-density ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed ...

Physicists have demonstrated that even relatively large metallic nanoparticles can exist in quantum superposition, behaving like waves spread across space rather than fixed objects. Credit: ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

X-ray diffraction (XRD) is a powerful non-destructive analytical technique used to evaluate crystalline materials and determine their structural properties. As one of the most widely used ...

Ph.D.(St.And.), B.Sc.(Exon.), Sc.D.(Dub.), F.R.S. See Professor Sir Michael Berry's website for more details. Many incompletely understood phenomena lurk in the ...

Abstract: Interference and diffraction of light are elementary topics in optics. The aim of the work presented here is to develop an accurate and cheap optical-system simulation software that provides ...

With the super-election year of 2024 in the rearview mirror, there is a lot to learn from the elections that have taken place in Europe during a period of increasing geopolitical tensions. In ...
