预热时的原始磁场

Primordial magnetic fields at preheating

A. Diaz-Gil, J. Garcia-Bellido, M. Garcia Perez, A. Gonzalez-Arroyo

摘要:

利用晶格方法研究了冷电弱跃迁过程中长程宇宙磁场的产生。我们将展示在气泡碰撞过程中,磁场是如何以磁弦的形式出现的。我们推测,这些磁弦起源于与EW斯佩勒龙状配置相关的磁偶极子的排列。我们还讨论了光子的早期热化和快子预热后的标量场的湍流行为。

英文摘要:

Using lattice techniques we investigate the generation of long range cosmological magnetic fields during a cold electroweak transition. We will show how magnetic fields arise, during bubble collisions, in the form of magnetic strings. We conjecture that these magnetic strings originate from the alignment of magnetic dipoles associated with EW sphaleron-like configurations. We also discuss the early thermalisation of photons and the turbulent behaviour of the scalar fields after tachyonic preheating.
