Building better electron sources with graphene

Photocathodes that produce electron beams for electron microscopes and advanced accelerators can be refreshed and rebuilt repeatedly without opening the devices that rely on them, provided the electron emitting materials ...

Electrons losing weight

The measured mass of electrons in solids is always larger than the value predicted by theory. The reason for this is that theoretical calculations do not account properly for various interactions with other electrons or lattice ...

Resolving the high pressure phases of calcium

(PhysOrg.com) -- Significant experimental and theoretical work has been devoted to the electronic, structural and superconducting properties of calcium (Ca) at high pressure.

LHCb's new analysis confirms old puzzle

Today, at the 50th Moriond Electroweak conference (link) (La Thuile, Italy), LHCb physicists presented their latest analysis of the rare B → K*μμ decay. The new results show deviations from Standard Model calculations.
