论文摘要
Yukawa的相互作用可以介导早期宇宙中费米子之间相对较长的吸引力。这种具有全球吸引力的相互作用会导致不稳定，即使在辐射占据主导的时代，也会导致受影响物种的结构增长。费米子微哈洛斯（Fermionic Microhalos）的形成和崩溃会在崩溃的光环的地点造成热火球，从而将能量注入宇宙等离子体。在本文中，我们研究了可能在此类模型中发生的新现象。我们表明，注入的能量可以部分转换为原始磁场，并估计相关量表和这些场的功率谱。我们表明它们可能是观察到的天体物理磁场的种子。
Yukawa interactions can mediate relatively long-range attractive forces between fermions in the early universe. Such a globally attractive interaction creates an instability that can result in the growth of structure in the affected species even during the radiation dominated era. The formation and collapse of fermionic microhalos can create hot fireballs at the sites of the collapsing halos which inject energy into the cosmic plasma. In this paper we study a new phenomena which can take place in such models. We show that the injected energy can be partially converted into primordial magnetic fields and we estimate the correlation scale and the power spectrum of these fields. We show that they may be the seeds of the observed astrophysical magnetic fields.
