Line junctions in the quantum Hall effect - Penn Physics
... Edge states in the quantum Hall effect offer a highly controlled laboratory for the experimental study of quantum transport in one dimension. The right and left moving edge modes, which reside on the opposite edges of a quantum Hall bar form an ideal one-dimensional electron gas. Since the edges are ...

QUANTUM FIELD THEORY
... when one has an infinite time available. For a particle in interaction, the momentum changes with time and a measurement over a long time interval is meaningless. The only case in which the momentum of a particle can be measured exactly is when the particle is free and stable against decay. In this ...

In very short contacts, the transition to a well defined quasi-bound state does not take place at all: as the two polarized regions merge at the centre of the QPC, the conductance has already reached the first plateau.

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.
