Haag`s Theorem in Renormalisable Quantum Field Theories
... Yet it was decided that it is an apt title, if one lets ’Haag’s theorem’ stand for the triviality results that preclude a mathematically rigorous nonperturbative definition of interacting quantum field theories. There are a vast number of more or less viable attempts to give QFT a sound mathematical ...

Complexity Science as Order-creation Science
... He shows that decoherence is “an irreversible dynamical process” (Omnès, 1999: 206). Complexity scientists should note the parallel of Omnès’s and Prigogine’s treatment of time irreversibility (Prigogine & Stengers, 1984). Omnès suggests a total Hamiltonian: H = Hc + He + H1, where Hc is the Hamilto ...

Gap Evolution in \nu=1/2 Bilayer Quantum Hall Systems
... At ¼ 2=3, the gap shows a downward cusp behavior which indicates a clear transition from a two-component state to a one-component state. However, at ¼ 1=2 such a characteristic was not observed. Since the gap first increases when tunneling amplitude SAS is decreased, they considered the two-comp ...

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.
