ELECTROMAGNETIC radiationWhen a fast charged particle enters a single crystal, the plane wave function of the free particle is transformed into a superposition of the localized wave functions associated with bound transverse motion in the channeling states. Transition of a free p...
This is the quantum electrodynamical explanation for the absence of radiation from the supported charge. It is not enough that photons are there; to be observable, they must be of the transverse kind, and this property (like the nonvanishing of a magnetic field) is not ...

The radiation of interface waves by the interaction of the rupture with an edge of the fault (Case 4) is not studied in detail here, albeit it is clearly apparent in almost all the events (Figure 2 and Figure S2 in Supporting Information S1). It has been observed and studied in detail...
