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 ...

MAT COWARD offers a roll call of refuseniks – some for political reasons, others for quirky reasons of their own ...

Ninety-seven years ago this month, 25--year-old physicist Paul Dirac was working on an elegant equation that would lay the foundation for quantum electrodynamics and earn him a The Nobel Prize.

The spin-zero particles like the mesons are satisfactorily described by the KG equation while the spin-half particles such as the electrons are described by the Dirac equation. It is therefore of ...

If you think Quantum Computing (QUBT) does quantum computing, you’re in for a surprise… It doesn’t. After much changing of ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their parent atom or molecule.
