Separability of test fields equations on the C-metric background (1603.01451v1)

Abstract: In the Kerr-Newman spacetime the Teukolsky master equation, governing the fundamental test fields, is of great importance. We derive an analogous master equation for the non-rotating C-metric which encompass massless Klein-Gordon field, neutrino field, Maxwell field, Rarita-Schwinger field and gravitational perturbations. This equation is shown to be separable in terms of "accelerated spin weighted spherical harmonics". It is shown that, contrary to ordinary spin weighted spherical harmonics, the "accelerated" ones are different for different spins. In some cases, the equation for eigenfunctions and eigenvalues are explicitly solved.
