Electronic order in quantum materials often emerges not uniformly, but through subtle and complex patterns that vary from ...

The mystery of quantum phenomena inside materials—such as superconductivity, where electric current flows without energy loss—lies in when electrons move together and when they break apart. KAIST ...

Is it possible to 3d print a diffraction pattern? Chong Wei confirms Seu Bock as singles head coach, salary hike proposal for coaches Museum changes Trump portrait plaque, sparks debate MACC records ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

A Python package for calculating X-ray diffraction (XRD) and ultrafast electron diffraction (UED) signals from molecular geometries and trajectories using the Independent Atom Model (IAM) ...

ABSTRACT: This paper serves two purposes. Firstly, we show how the classical mechanics of Newton—where momentum energy is less than rest mass energy, pc≪ m o c 2 = E o —transitions with increasing ...

A new method using spiraling electron beams allows scientists to directly observe electrons in motion, unlocking new insights into quantum processes and molecular behavior. Credit: SciTechDaily.com ...

Electrons oscillate around the nucleus of an atom on extremely short timescales, typically completing a cycle in just a few hundred attoseconds (one attosecond is a quintillionth of a second). Because ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...
