虚磁场及其在暴胀中的原始起源

Void magnetic field and its primordial origin in inflation

Tomohiro Fujita

摘要:

由于星系、星系团甚至空区中的磁场都被观测到了,因此从理论上解释其起源的努力受到了强烈的推动。有趣的是,暴胀是造成磁场和密度扰动的原因。然而,众所周知,暴胀磁生有几个问题。我们探讨这些问题,通过使用一个特定的模型,即动力学耦合模型,并显示该模型是如何受到约束。模型独立的参数进行了讨论。

英文摘要:

Since magnetic fields in galaxies, galactic clusters and even void regions are observed, theoretical attempts to explain their origin are strongly motivated. It is interesting to consider that inflation is responsible for the origin of the magnetic fields as well as the density perturbation. However, it is known that inflationary magnetogenesis suffers from several problems. We explore these problems by using a specific model, namely the kinetic coupling model, and show how the model is constrained. Model independent arguments are also discussed.
