We use dimensional regularization to compute the one loop quantum gravitational contribution to the vacuum polarization on de Sitter background. Adding the appropriate BPHZ counterterms gives a fully renormalized result which can be used to quantum correct Maxwell's equations. We use the Hartree approximation to argue that the electric field strengths of photons experience a secular suppression during inflation.

  1. Cancellation of one-parameter graviton gauge dependence in the effective scalar field equation in de Sitter

    hep-th 2026-02 unverdicted novelty 5.0

    Gauge dependence cancels in the one-loop effective scalar equation in de Sitter when all diagram contributions including external mode corrections are collected.

  2. Graviton propagator in de Sitter space in a simple one-parameter gauge

    gr-qc 2025-11 unverdicted novelty 5.0

    Derives a relatively simple graviton propagator in de Sitter space for a one-parameter family of non-covariant gauges to enable gauge-dependence checks in loop computations.
