论文摘要
宇宙中磁场的存在是明确的。从恒星到星系簇的所有尺度上都可以观察到它们。但是，这些领域的起源仍然是神秘的。人们认为，在某些条件下，磁场种子可能从通货膨胀中出现。这种可能性是在替代性重力理论的背景下与曲率和物质之间非最小耦合的背景。通过在非最小模型的背景下，通过解决通用的麦克斯韦方程的解决方案，对于一般的慢速通货膨胀方案，重新加热的温度较低，$ t_ {rh} \ simeq10^{10} $ gev，可以使生成的磁场在大型鳞片中兼容，$ s sims $ ccc $ 1 mpc $。
The existence of magnetic fields in the universe is unmistakable. They are observed at all scales from stars to galaxy clusters. However, the origin of these fields remains enigmatic. It is believed that magnetic field seeds may have emerged from inflation, under certain conditions. This possibility is analised in the context of an alternative theory of gravity with non-minimal coupling between curvature and matter. We find, through the solution of the generalised Maxwell equations in the context of non-minimal models, that for general slow-roll inflationary scenarios with low reheating temperatures, $T_{RH}\simeq10^{10}$GeV, the generated magnetic fields can be made compatible with observations at large scales, $λ\sim 1 Mpc$.
