Minkowski时空中的精确隧穿解和暗能量的候选者

Exact Tunneling Solutions in Minkowski Spacetime and a Candidate for Dark Energy

Georgios Pastras

摘要:

本文研究了由线性或二次曲面构成的势垒在标量场理论中的精确隧穿解。为了研究气泡内部标量场的分布,我们解析地将我们的解继续到虚欧几里德半径。我们发现,一般有一个非平凡的配置文件的标量场,产生应力能量张量,这取决于潜在的形式,可以是一个候选人的暗能量。

英文摘要:

We study exact tunneling solutions in scalar field theory for potential barriers composed of linear or quadratic patches. We analytically continue our solutions to imaginary Euclidean radius in order to study the profile of the scalar field inside the growing bubble. We find that generally there is a non-trivial profile of the scalar field, generating a stress-energy tensor, that depending on the form of the potential, can be a candidate for dark energy.
