Electrodynamical response of a high-energy photon flux to a gravitational wave

The electrodynamical response of a high-energy photon flux (strong electromagnetic wave) propagating in a static magnetic field to a standing gravitational wave (GW) is studied. The corresponding perturbation solutions and resonant conditions are given. It is found that, for the electromagnetic wave with a frequency ${\omega }_e$ and a standing GW with ${\omega }_g,$ the perturbed electromagnetic fields will contain three new components with frequencies $|{\omega }_e\pm {\omega }_g|$ and ${\omega }_g,$ respectively. The resonant response occurs in two cases of ${\omega }_e=1/2\mathrm{}{\omega }_g$ (half-frequency resonance) and ${\omega }_e={\omega }_g$ (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 perpendicular to the propagating direction of the background electromagnetic wave. This effect might provide a new possibility for the electromagnetic detection of GWs. Moreover, the possible schemes of displaying perturbed effects induced by the high-frequency standing GW at the level of the single photon avalanche and in typical laboratory dimensions are reviewed.
