论热弦气的成因

On the origin of thermal string gas

Kari Enqvist, Niko Jokela, Esko Keski-Vakkuri, Lotta Mether

摘要:

我们研究了衰变D-膜作为弦气宇宙学中热弦气的起源。我们考虑低维膜的初始配置,并认为它们可以时间演化为热弦气体。我们发现,有一个范围内的弱弦耦合和快速膜衰变时间制度,在初始配置可以驱动的演化值,正好有三个类空方向变大。

英文摘要:

We investigate decaying D-branes as the origin of the thermal string gas of string gas cosmology. We consider initial configurations of low-dimensional branes and argue that they can time evolve to thermal string gas. We find that there is a range in the weak string coupling and fast brane decay time regimes, where the initial configuration could drive the evolution of the dilaton to values, where exactly three spacelike directions grow large.
