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 ...

An algorithm that enables a protein's molecular structure to be determined from the faintest of diffraction patterns could increase the potential of next-generation X-ray sources. The next few years ...

The goal of this project was to implement something akin to James Holton's authoritative nanobragg x-ray diffraction simulator in numpy. This was undertaken mostly as a learning exercise and a ...

Abstract: Sunmary form only given. Scattering by semi-infinite cone obstacles is a fundamental canonical problem in wave theory [1]-[2]. The formal exact solution to this problem is given by an ...

Test for echo: schematic diagram of an object to be imaged (blue blob) and illumination source (concentric circles) inside a randomly shaped cavity. The detector is represented by the two parallel ...

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 ...

Distinguished for his pioneering studies in X-ray diffraction physics, especially for his development of the technique of X-ray topography, Andrew Lang will be greatly missed by many researchers for ...

Is there a relationship between seemingly random prime numbers and the physical world? A study published today by Monash physicists in Physical Review Letters, suggests there might be. The research ...
