My name is Juan Ramón González Álvarez. I studied physics and chemistry at UVIGO, worked for some scientific bodies such as ANQUE, did early research in biogeochemistry and hydrodynamics of rias at CSIC, but now work in a unified formulation of physics chemistry and biology. My last research can be found at academia.edu

I am the owner of juanrga.com.

comment Field energy of/from virtual Photons
@NoEscape The above Hamiltonian describes the whole electromagnetic field was either isolated and static or interacting with matter. I think you are referring to the Coulomb interaction, but this is considered part of the matter-field interaction.

comment Field energy of/from virtual Photons
@NoEscape How could it be? My answer states that EM field is made of real photons. And the link explains why the usual argument that real photons are in reality virtual doesn't hold up.

comment What does the equivalence principle mean in quantum cases?
@WetSavannaAnimalakaRodVance Thanks by kindly words. Davies paper just confirms that the equivalence principle applies when quantum effects are neglected, which was my point.

Now just compute the average of $v^2$ and you will obtain $c^2$, which correspond to a Dirac particle moving at $\pm c$
