A new calculation of the electron's self-energy improves determination of fundamental constants
When quantum electrodynamics, the quantum field theory of electrons and photons, was being developed after World War II, one of the major challenges for theorists was calculating a value for the Lamb ...

Scientists in Germany said Wednesday they had made the most precise measurement yet of the mass of the electron, one of the building blocks of matter. The feat should provide a useful tool for ...
In solid materials, when an electron changes position without another to fill its place, a positively charged 'hole' can appear which is attracted to the original electron. In more complex situations, ...
