No point-localized photon states [article]

Scott E. Hoffmann
2020 arXiv   pre-print
Then it is found that the authors making these claims use a non-standard scalar product, not equal to the quantum-mechanical one.  ...  The aim of this paper is to critically examine claims that it is possible to construct point-localized state vectors for the photon. We supply a brief proof of the impossibility of this.  ...  Orthogonality of state vectors with different values of the index would be required to complete the proof, but no such result is given and would clearly not be possible.  ...

Dark energy, non-minimal couplings and the origin of cosmic magnetic fields

Jose Beltrán Jiménez, Antonio L Maroto
2010 Journal of Cosmology and Astroparticle Physics  
This implies that in the presence of dark energy, the motion of large-scale structures generates magnetic fields.  ...  Imposing the consistency of the theory in the weak-field limit, we show that it reduces to standard electromagnetism in the presence of an effective electromagnetic current which is generated by the momentum  ...  Indeed, this type of fields can be amplified from quantum fluctuations during inflation in a completely analogous way to metric perturbations.  ...
