论文摘要
麦克斯韦电磁理论嵌入了不均匀的莱玛\^ıtre-tolman-bondi(ltb)时空背景,几年前在文献中描述了。但是,没有探索有关质量或高衍生品的术语。在这项工作中,我们研究了对高衍生物和大量电磁模型的不均匀时空影响。我们使用了LTB度量,并计算了对Proca和更高衍生的Podolsky模型的感兴趣的物理量,即电磁场的比例因子,电磁场的密度和哈勃常数。我们在两个模型中都发现了一个新的奇异性,并且在Proca模型中磁场必须为零。
The Maxwell electromagnetic theory embedded in an inhomogeneous Lema\^ıtre-Tolman-Bondi (LTB) spacetime background was described a few years back in the literature. However, terms concerning the mass or high-derivatives were no explored. In this work we studied the inhomogeneous spacetime effects on high-derivatives and massive electromagnetic models. We used the LTB metric and calculated the physical quantities of interest, namely the scale factor, density of the electromagnetic field and Hubble constant, for the Proca and higher-derivative Podolsky models. We found a new singularity in both models, and that the magnetic field must be zero in the Proca model.
