标量场、局域结构与 Starobinsky 模型

Scalar fields, localized structures and the Starobinsky model

D. Bazeia, Elisama E. M. Lima

AI总结:

本文在二维相对论实标量场中研究标准与修正运动学下的局域静态结构,利用可将 kink 变为 compacton 的势及 Starobinsky 势,得到更丰富的解并发现特定紧致构型的 twinlike 行为。

摘要:

本工作研究实线上局域静态结构的存在,这些结构由二维时空中的相对论性实标量场描述。我们考虑同时具有标准运动学和修正运动学的模型,并采用两个支持缺陷解的有趣势。第一个势在标准框架内可将 kink(扭结)转变为 compacton(紧孤子),而第二个势基于暴胀 Starobinsky 模型。文中描述了以往研究中未曾见到的有趣可能性,尤其是在与 Starobinsky 势相关的情形中。所讨论的势被纳入一个更广泛的框架,因此扩展模型由更丰富的解集描述。本研究还揭示了特定紧致构型存在孪生(twinlike)行为,该构型可求解两个不同的模型。

英文摘要:

This work deals with the presence of localized static structures in the real line, described by relativistic real scalar fields in two spacetime dimensions. We consider models featuring both standard and modified kinematics, where we employ two intriguing potentials supporting defect solutions. The first potential can transform kink into compacton in the standard framework, while the second one is based on the inflationary Starobinsky model. Interesting possibilities unseen in previous investigations are described, in particular, for the case related to the Starobinsky potential. The addressed potentials are inserted into a broader framework, and so the extended models are described by a wider set of solutions. This investigation also reveals the presence of the twinlike behavior for a specific compact configuration, which solves two distinct models.
