标题： Uniform rate inflation in $f(T, \mathcal{T})$-gravity

摘要： 我们提出了在修改的$f(T, \mathcal{T}) $引力中的统一速率膨胀。 发现即使标量场具有二次势和负宇宙常数，也可以实现早期膨胀。 我们构建了一个不使用慢滚近似的暴胀场模型。 暴胀场以恒定速度滚动允许一个具有足够膨胀的宇宙，该宇宙很好地涵盖了当前宇宙。 标量的初始值满足一个下限，该下限相对于混沌暴胀所需的场来说足够大。 估计了普朗克对宇宙学扰动的预测。 发现该宇宙学模型是稳定的。 显示英文摘要

摘要： We present uniform rate inflation in a modified $f(T, \mathcal{T}) $ gravity. It is found that early inflation can be realized even with a scalar field field with a quadratic potential and a negative cosmological constant. We construct inflationary model for the inflaton field without slow-roll approximation. The inflaton field rolling at a constant speed permits a universe with sufficient inflation which encompasses the present universe fairly well. The initial value of the scalar satisfies a lower limit which is sufficiently large compared to the field required for chaotic inflation. The Planck prediction for cosmological perturbations are estimated. It is found that the cosmological model is stable.
