Highly charged heavy ions form a very suitable experimental field for investigating quantum electrodynamics (QED), the ...

This interaction is determined largely by the electronic structure of atoms and molecules; photon absorption or emission is associated with an electron moving from one energy level to another.

Main repository for QMCPACK, an open-source production level many-body ab initio Quantum Monte Carlo code for computing the electronic structure of atoms, molecules, and solids with full performance ...

SCIENCE is steadily becoming severely specialised. The proportion of amateurs (in the restricted sense of the word) among original workers of all ranks decreases slowly but surely. The average ...
