Probing Modified Gravity and Non-Abelian Gauge Fields by Gravitational Waves

通过GWS探测暗扇区：我们得到了包含轴子和暗光子效应的随机引力波(GW)谱的解析表达式。我们在《高能物理杂志》(JHEP)上发表了这一结果。暗光子暗物质：我们已经证明，暗光子可以在膨胀过程中产生，并在以后扮演暗物质的角色。我们在JHEP.非形式变换和Petrov分类中发表了结果：我们已经证明了当标量张量和矢量张量理论中的Petrov型解在保形变换下保持不变时，它在非形变换下可以改变。我们在《宇宙学与天体粒子物理杂志》(JCAP)上发表了这一结果。

Probing dark sector via GWs: We have obtained an analytical expression for the stochastic gravitational wave (GW) spectrum which includes the effects of axions and dark photons. We published the result in Journal of High Energy Physics (JHEP).Dark photon dark matter: We have shown that dark photons can be produced during inflation and play the role of dark matter later. We published the result in JHEP.Disformal transformation and Petrov classification: We have shown that while a Petrov type of a solution in scalar-tensor and vector-tensor theories remain unchanged under a conformal transformation, it can change under a disformal transformation. We published the result in Journal of Cosmology and Astroparticle Physics (JCAP).
