Abstract The evolutionary pictures of tachyon field in modified loop cosmology have been investigated. We present the dynamical behavior of the tachyon field associated with an exponential potential and find that the pre-inflation dynamics are very similar in both modified loop cosmology and standard loop quantum cosmology. In addition, tachyonic inflation in modified loop cosmology models are discussed, and we find that the probability of inflation in modified loop cosmology is very closer to 1.

环形宇宙学中的快子场

摘要 研究了修正环宇宙学中快子场的演化图。我们展示了与指数势相关的快子场的动力学行为，并发现膨胀前动力学在修正环宇宙学和标准环量子宇宙学中非常相似。此外，还讨论了修正环宇宙学模型中的快速暴胀，我们发现修正环宇宙学中暴胀的概率非常接近于 1。
