Coulomb Potential in Podolsky-Carroll-Field-Jackiw Electrodynamics

D. S. Cabral, L. A. S. Evangelista, A. F. Santos

Podolsky electrodynamics, a higher-derivative extension of Maxwell's theory characterized by the Podolsky parameter $I^» = 1/ m$ , which modifies the photon dispersion relation and regu…

Time-Machines Construct in $f (R, A, A^{I^¼ I^½} A_{I^¼ I^½})$ and $f (R)$ Modified Gravity Theories

F. Ahmed, J. C. R. de Souza, A. F. Santos

In this paper, our objective is to explore a time-machine space-time formulated in general relativity, as introduced by Li (Phys. Rev. D {\bf 59}, 084016 (1999)), within the contex…
