论文摘要
假定在通货膨胀时期存在的热波动可以使充气标量场与其他场相互作用,从而在通货膨胀期间存在热成分。这种热成分的存在有助于结构形成,并减少了当代通货膨胀范式中的重新加热依赖性。这被称为温暖的通货膨胀。 1990年D. Barrow \ cite {25}考虑了一种通货膨胀的情况,物质场具有具有$ p+p+ρ=γρ^λ,〜γ \ neq 0 $和$λ$常数状态的现象学方程。他称这种通货膨胀率是“毕业通货膨胀”。在这项工作中,我们在温暖通货膨胀的情况下重新考虑了上述状态方程。我们的目的是调查并了解此事是否也可以作为温暖通货膨胀的可行候选人。
It is presumed that thermal fluctuations present during inflationary epoch can make inflaton scalar field to interact with other fields resulting in the existence of a thermal component during the inflationary period. The presence of this thermal component assists structure formation and reduces reheating dependence as in the contemporary inflationary paradigm. This is known as warm inflation. In 1990 J . D. Barrow \cite{25} considered a scenario of inflation with matter field having a phenomenological equation of state of the type $p+ρ=γρ^λ,~γ\neq 0$ and $λ$ constant. He called such inflationary scenarios as "graduated inflation". In this work we reconsider the above equation of state in a scenario of warm inflation. Our aim would be to investigate and understand whether such matter can also act as a viable candidate for warm inflation.
