快子暴胀的Hamilton-Jacobi形式
Hamilton-Jacobi Formalism for Tachyon Inflation
摘要：
利用普朗克2013和BICEP 2的观测数据重新考虑了超光速粒子暴胀。Hamilton-Jacobi形式主义被挑选出来作为一个可取的方法在这项工作中，它允许一个容易地获得的模型的主要参数。假设哈勃参数是标量场的幂律和指数函数，并分别考虑每种情况。在工作过程中解释了模型的约束条件，这些约束条件来自观测数据。结果给出了张量谱指数的合适值和势的适当形式。
英文摘要：
Tachyon inflation is reconsidered by using the recent observational data obtained from Planck-2013 and BICEP2. The Hamilton-Jacobi formalism is picked out as a desirable approach in this work, which allows one to easily obtain the main parameters of the model. The Hubble parameter is supposed as a power-law and exponential function of the scalar field, and each case is considered separately. The constraints on the model, which come from observational data, are explained during the work. The results show a suitable value for the tensor spectral index and an appropriate form of the potential.
