论文摘要
除了宇宙常数外，还认为在各向同性和均匀时空的背景下，最一般的作用被认为是研究早期宇宙的量子演变。在存在曲率平方术语的情况下，有效的哈密顿运算符的墓穴表明了量子状态的单一时间演变，从而确保了概率的保护。半古典波函数围绕开发液的振荡行为，该解决方案是经典允许的，而宇宙在普朗克时代就进入了通货膨胀制度。鉴于哈勃流量参数的层次结构，并使用重新定义的有效电势，在存在几个耦合参数的情况下，复杂的经典场方程将其缩减为具有单个标量场字段的标准通用 - 偏好方程。结果，已经研究了通货膨胀，而没有考虑任何其他流程参数。通货膨胀参数非常在于目前可用的普朗克数据，该模型承认优雅地退出了通货膨胀。
Possibly, the most general action in the background of isotropic and homogeneous space-time has been considered to study the quantum evolution of the early universe, apart from a cosmological constant. The hermiticity of the effective Hamiltonian operator in the presence of curvature squared terms suggests unitary time evolution of the quantum states, assuring conservation of probability. The oscillatory behaviour of the semi-classical wavefunction around a de-Sitter solution signals that the theory is classically allowed, and the universe enters an inflationary regime just after Planck's era. In view of a hierarchy of Hubble flow parameters, and using a redefined effective potential, the complicated classical field equations in the presence of several coupling parameters, reduce to standard general-relativistic equations with a single scalar field. As a result, inflation has been studied without considering any additional flow parameters. Inflationary parameters lie very much within the presently available Planck's data, and the model admits graceful exit from inflation.
