摘要

畴壁是在各种新的物理模型中离散对称性自发破缺而产生的二维拓扑缺陷。在这项研究中，我们首次计算了由畴壁网产生的标量扰动产生的引力波。我们的发现表明，引力波的频谱与其他来源的明显不同。这为未来旨在探索畴壁在早期宇宙中的作用的引力波实验开辟了一条有希望的途径。

Scalar-induced gravitational wave from domain wall perturbation

Domain walls represent two-dimensional topological defects that emerge from the spontaneous breaking of discrete symmetries in various new physics models. In this study, we undertake the first calculation of gravitational waves produced by scalar perturbations generated from the domain wall network. Our findings indicate that the gravitational wave spectrum is notably distinct from that of other sources. This opens up a promising avenue for future gravitational wave experiments aimed at exploring the role of domain walls in the early universe.

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
