“旧”锁定通货膨胀

"Old" Locked Inflation

Yang Liu, Yun-Song Piao, Zong-Guo Si

摘要:

在本文中,我们重新审视的想法锁定通货膨胀,它不需要一个潜在的满足正常的慢滚条件,但遭受的问题与“鞍通货膨胀”。我们提出了一个方案的基础上锁定通货膨胀,但是,与“瀑布场”$ϕ$的替代演变机制。$ϕ$场不再沿着势向下滚动,而是像旧的暴胀那样隧穿以结束暴胀阶段,由此可以避免鞍状暴胀。此外,我们研究了一个级联的旧的锁定通货膨胀,这可以激发弦景观。我们的模型是基于使锁定暴胀可行的考虑,从而给出一个没有慢滚的工作模型;它也可以被看作是将旧暴胀嵌入弦景观的努力。

英文摘要:

In this paper, we revisit the idea of locked inflation, which does not require a potential satisfying the normal slow-roll condition, but suffers from the problems associated with "saddle inflation". We propose a scenario based on locked inflation, however, with an alternative evolution mechanism of the "waterfall field" $ϕ$. Instead of rolling down along the potential, the $ϕ$ field will tunnel to end the inflation stage like in old inflation, by which the saddle inflation could be avoided. Further, we study a cascade of old locked inflation, which can be motivated by the string landscape. Our model is based on the consideration of making locked inflation feasible so as to give a working model without slow roll; It also can be seen as an effort to embed the old inflation in string landscape.
