AI 中文摘要
本研究在三维加一维的广义相对论框架下引入了精确宇宙学解，该解同时考虑了常规流体成分与描述超流体π介子涡旋的超流体成分。这类超流体涡旋是不均匀性的来源，可被精确处理，无需使用微扰理论。这些解析解对获取宇宙学中不均匀性的非微扰描述具有重要意义。我们分析了这类宇宙学背景下，这些强子不均匀性对电磁场传播的特殊效应，并探讨了可能的可观测效应。最后，我们讨论了这类解存在所需的有效超流体满足的性质，以及该解族可能的扩展方向。
英文摘要
In this work we introduce exact cosmological solutions in General Relativity in (3+1) dimensions which take into account both the usual fluid component as well as a superfluid component describing superfluid Pionic vortices. Such superfluid vortices are source of inhomogeneities which can be treated exactly, no perturbation theory is required. These analytic solutions are relevant to obtain a non-perturbative description of inhomogeneities in cosmology. We discuss the peculiar effects of these hadronic inhomogeneities on the propagation of electromagnetic fields on such cosmological backgrounds analyzing possible observable effects. Finally, the properties that the effective superfluid satisfy for such solutions to exist are discussed, together with possible extensions of this family of solutions.
