Dirac electrons were predicted by P. Dirac and discovered by A. Geim, both of whom were awarded the Nobel Prize in Physics in 1933 and in 2010, respectively. Dirac electrons behave like photons ...

Raman spectroscopy experiments show that the interaction between electrons and phonons in graphene resembles the Dirac fermion–photon coupling ... in metals is related to the emergence of ...

The amount of kinetic energy the electron has depends on the difference between the energy of the photon and the work function of the metal. The kinetic energy of the electron is equal to the ...

Observations such as the rubidium atoms becoming excited despite photons passing through the cloud, and emitting a photon before the electrons ... of photonics and related fields, none of which ...

When quantum electrodynamics, the quantum field theory of electrons and photons ... the energy of a photon resulting from an electron transitioning from one hydrogen hyperfine energy level ...

This energy is released as a photon. The energy of the photon can ... Continuous spectra are produced by electrons being shared between many atoms, giving a huge range of possible frequencies ...
