论文摘要
我们研究了一个由反对称张量场三联的通货膨胀模型，具有最小的和非最小值的耦合。首先，我们表明，与使用反对称的张量张量场相反，与过去的研究相反，在应力能量张量中的存在三联体可以提供固有的背景各向同性。在存在与重力的非最小耦合的情况下，支持通胀。我们执行慢速分析，并分析对抗对称张量场以及扰动度量的张量模式的扰动。从张量扰动中表现出的引力波的速度被调整为$ c $。我们还研究了重力波的演变，计算其功率谱和张量光谱指数。
We study an inflation model driven by a triplet of antisymmetric tensor fields, with minimal and nonminimal couplings to gravity. First, we show that the presence of a triplet of antisymmetric tensor fields can provide inherent background isotropy in the stress-energy tensor contrary to the past studies using an antisymmetric tensor field. Inflation is supported in the presence of non-minimal couplings with gravity. We perform the slow roll analysis and also analyse perturbations to the antisymmetric tensor field as well as the tensor modes of perturbed metric. The speed of gravitational waves manifested from the tensor perturbations is tuned to $c$. We also study the evolution of the gravitational waves, calculate their power spectrum and tensor spectral index.
