A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not ...

DLR researchers have succeeded, for the first time, in diffracting matter waves of atoms through a solid; until now, this had only been possible with electrons and neutrons. This opens up new avenues ...

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 ...

Crystallography is the study of the atomic structures of crystals, where the diffraction or reflection of x-rays through the crystal is used to determine the crystal's internal structure. Crystal ...

This is a preview. Log in through your library . Abstract The diffraction of axisymmetric, harmonic elastic waves by a circular crack is considered. It is shown that the potential functions for the ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 209, No. 1096 (Oct. 8, 1951), pp. 81-96 (16 pages) The radio waves from 'radio stars' may suffer ...

Scientists recreated one of the most important experiments in the history of physics—but this time, they used antimatter instead of regular matter. All matter particles have a corresponding antimatter ...

IN usual experiments with diffraction of X-rays by crystals, an effect of space-lattice is always observed owing to the penetration of the rays into the depth of the crystal. The thin layers, however, ...

A new experiment captures a single parcel of light morphing between wave and particle. Published in the April Physical Review A, the experiment dissects a light pulse associated with a single photon ...
