在宇宙学背景下超弦理论的最新发展的激励下,我们研究了一个包含三向结弦网络的场论。我们对该模型进行了数值模拟,确定了形成的网络的长度尺度,并提供了证据,证明长度尺度趋向于缩放制度,与时间成比例增长。我们推断,结的存在本身并不会导致超弦网络支配早期宇宙的能量密度。
Motivated by recent developments in superstring theory in the cosmological context, we examine a field theory which contains string networks with 3-way junctions. We perform numerical simulations of this model, identify the length scales of the network that forms, and provide evidence that the length scales tend towards a scaling regime, growing in proportion to time. We infer that the presence of junctions does not in itself cause a superstring network to dominate the energy density of the early Universe.
