Title: Holographic QCD and Gravitational Waves

Abstract: I will first review basic properties of the Sakai-Sugimoto model, the top-down holographic theory closest to QCD. Then, in this model I will describe the process of nucleation of bubbles of true vacua in the case of two first-order transitions: the confinement/deconfinement and chiral symmetry breaking/restoration ones. Finally, using these information, I will present the calculation of the gravitational wave spectra generated in these transitions, when the Sakai-Sugimoto model is employed as a dark sector. Prospects of detection will be discussed.
