... a degeneracy in the energy levels, since there are two states with the same energy. This is referred to as an “exchange degeneracy”. However, it is experimentally observed that a pair of identical particles is always in an eigenstate of P12 , and that eigenstate depends only on the kind of particle. ...

Symmetry breaking and the deconstruction of mass
... The explanation of the mass of protons and neutrons is a fascinating story that is once again related to symmetry breaking. The symmetries involved are known as chiral symmetry and scale invariance. An excellent and accessible account is provided in a recent article by Wilczek [15]. We simply outlin ...

Ambiguous model learning made unambiguous with 1/f priors
... Previous studies [3] have reduced the problem of optimal interpretation of an ambiguous stimulus to the problem of estimating a single variable which may vary in time α(t), given a time sequence of noisy data. Enforcing a prior belief that the local dynamics α(t) should not vary too rapidly embodies ...

Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction.In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it ""the jewel of physics"" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.
