7.3: In Depth- Atomic-scale Particles and Waves
WEBJul 16, 2022 · How could the model work so well for a hydrogen atom and one-electron ions, but not accurately predict the emission spectrum for helium or any atom or ion with two or more electrons? To answer such questions, we need to explore the unusual properties of matter at the atomic scale.
Toward atomic-scale understanding of structure-dynamics …
WEBIn this review, we focus on the metallic glasses (MGs) and models alike, because of their relatively simple atomic structures without the complex intramolecular effects in some other glasses. MGs can offer a testing ground for glass theories.
2 ATOMIC SCALE - The National Academies Press
WEBThe main limiting factors in computational atomic-scale research today are the number of atoms that can be treated and the length of the simulation. Parallel computers are becoming an important ingredient in the impetus to study larger systems.
