Electrodynamical response of a high-energy photon flux to a gravitational wave - art. no. 044018

The electrodynamic; response of a high-energy photon Aux (strong electromag netic wave) propagating in a static magnetic field to a standing gravitatio nal wave (GW) is studied. The corresponding perturbation solutions and reso nant conditions are given. It is found that, for the electromagnetic wave w ith a frequency omega(e) and a standing GW with w(g), the perturbed electro magnetic fields will contain three new components with frequencies \omega(e )+/-omega(g)\ and omega(g), respectively. The resonant response occurs in t wo cases of omega(e)=1/2 omega(g) (half-frequency resonance) and omega(e)=o mega(g) (synchroresonance) only. Then not only first-order axial perturbed power fluxes, which propagate along the same and opposite directions to the background electromagnetic wave, can be generated, but also the radial and tangential perturbed power fluxes can be produced. The latter are perpendi cular to the propagating direction of the background electromagnetic wave. This effect might provide a new possibility for the electromagnetic detecti on of GWs. Moreover, the possible schemes of displaying perturbed effects i nduced by the high-frequency standing GW at the level of the single photon avalanche and in typical laboratory dimensions are reviewed.
