On the Gravitationally Induced Schwinger Mechanism. (arXiv:0911.1099v1 [hep-th])

In this paper we will present very recent results obtained in the ambit ofquantum electrodynamics in curved spacetime. We utilize a newly developednon-perturbative heat kernel asymptotic expansion on homogeneous Abelianbundles over Riemannian manifolds in order to compute the one-loop effectiveaction » Full text »
