Low-energy limit in the anomaly-induced action and the semiclassical cosmological bounce
Wagno Cesar e Silva, Nicolas R. Bertini, Ilya L. Shapiro
In the recently proposed scenario, the cosmological bounce occurs because the initially contracting Universe is not empty. In the region close to singularity, matter contents of th…

Extending the Euler-Heisenberg action to include effects of local Lorentz-symmetry violating backgrounds
Wagno Cesar e Silva, João Paulo S. Melo, José A. Helayël-Neto
This work sets out to compute the corrections to the Euler-Heisenberg effective action that arise from spacetime-dependent background anisotropies that violate Lorentz symmetry. To…
