Analytical solutions of CPT-odd Maxwell equations in Schwarzschild spacetime
【摘要】 In this paper,we present the CPT-violating(CPTV) Maxwell equations in curved spacetime using the Newman-Penrose(NP) formalism.We obtain a semi-analytical solution to the Maxwell equations in Schwarzschild spacetime under the assumption that the CPT-odd(kAF)μ term exhibits spherical symmetry in the Schwarzschild background.By retaining only terms up to the linear order in the(kAF)μ coefficient,we obtain perturbative solutions by treating the solutions of the Lorentz-invariant Maxwell equations as the zerothorder approximation and incorporating the(kAF)μ terms jointly as an additional source term alongside the external charge current.Each resulting NP scalar field can be factorized into two components:the radial component,expressed in terms of hypergeometric functions,and the angular component,described by spin-weighted spherical harmonics.
