Optical near-field microscopies can achieve spatial resolutions beyond the diffraction limit, but they cannot match the atomic-scale resolution of electron microscopy. Here, the development of ...

Interesting Engineering on MSNPhysicists control dark excitons using lasers and magnetism to store quantum statesResearchers at the University of Innsbruck, along with those at Dortmund, Bayreuth, and Linz universities, have demonstrated ...
Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...
"The length of time between photon absorption and electron emission is very difficult to measure because it is only a matter of attoseconds," explains Till Jahnke, the PhD-supervisor of Jonas Rist.

In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a ...
The short pulses were necessary because of a two-photon absorption effect. Silicon atoms can absorb two photons simultaneously, generating an electron and a hole (the absence of an electron).
In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary ...
Researchers at the University of Gothenburg have observed the absorption of a single electron by a levitated droplet with such a magnification that it is visible with ...
Previous studies have shown that electron collimation using a photon MLC (pMLC) can achieve similar quality plans to cut-out collimation, for treatments with a reduced source-to-surface distance (SSD) ...
