Electronic transport in graphene nanostructures on SiO
... The inset of Fig. 2 shows a nanoribbon, 60 nm in width and 200 nm in length. The dependence of its conductance on the backgate voltage is shown in the main panel of Fig. 2 on a logarithmic scale. The conductance changes by about three orders of magnitude while the Fermi-energy is shifted from the va ...

While this is not astonishing in itself, there are a few notable properties that do make the neutron special among all baryons: It is electrically neutral, easy enough to produce and s ...

The Violation of Bell Inequalities in the Macroworld

This idea was first considered in Ae ...

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.
