Summary: Using a holographic derivation method, we compute quasiequilibrium parameters for the gravitational wave signal from a first-order phase transition in a simple dual model. We discuss how these parameters vary with the effective degrees of freedom of the dual field theory. If the critical temperature is around a TeV and the field theory exhibits approximate conformal symmetry, our model can produce an observable signal at LISA.

Summary: In this paper, we discuss the computation of the quantum effective action for strongly interacting field theories using holographic duality, and its application in determining the quasiequilibrium parameters of first-order phase transitions relevant for gravitational wave production. We introduce a simple holographic model that includes only the metric and a free massive scalar field. Despite its simplicity, the model exhibits a rich phase diagram with first-order phase transitions at nonzero temperature due to various multitrace deformations. By studying homogeneous black brane solutions and linearized perturbations, we obtain the leading terms in the effective action. We then use the effective action to construct bubble and domain wall solutions in the field theory and investigate their properties, particularly how the scaling of the effective action with the effective number of degrees of freedom determines the scaling of gravitational wave parameters.

Summary: The white paper outlines the challenges and gains expected in gravitational-wave searches, focusing on Ultra High-Frequency Gravitational Waves (UHF-GWs). The absence of known astrophysical sources in the UHF-GWs frequency range provides a unique opportunity to discover physics beyond the Standard Model. The report is a summary of a workshop held at ICTP Trieste, Italy, which set the stage for the Ultra-High-Frequency Gravitational Wave (UHF-GW) initiative.

Summary: Stochastic gravitational waves are produced in the thermal plasma of the early universe, with energy density scaling according to the maximum temperature and effective number of entropy degrees of freedom. Researchers have made state-of-the-art predictions for this Cosmic Gravitational Microwave Background (CGMB) and conducted calculations for various models, including both minimal and non-minimal extensions of the Standard Model. Discussions on current upper limits and prospects for detecting the CGMB in laboratory experiments were also presented.

Summary: The spectra of stochastic gravitational waves generated in cosmological first-order phase transitions are computed within strongly correlated theories with a dual holographic description. The study considers bubble collisions and sound waves arising from two types of first-order phase transitions and finds that the gravitational wave spectra may be within the sensitivity range of ground-based and space-based interferometers, as well as Pulsar Timing Arrays, depending on the model parameters. The research also explores characteristic spectra with double frequency peaks when two phase transitions occur at different critical temperatures.

Summary: Investigating first order phase transitions in a holographic setting, we explore the parameter space and physical quantities, finding a strong correlation between alpha and stiffness. We propose the potential observation of a TeV-scale hidden sector at future space-based detectors using a corrected gravitational wave power spectrum model.

Summary: In this study, the steady-state velocity of expanding vacuum bubbles nucleated within chiral finite temperature first-order phase transitions in strongly coupled large N QCD-like models is determined using holographic correspondence as a tool. The friction force exerted by the plasma on the bubbles and the steady-state velocity are calculated. The phase transitions are related to changes in the embedding of flavor branes probing the black hole background in a top-down holographic description.

Summary: Cosmological phase transitions occur via the nucleation, expansion, and collision of bubbles, with the resulting gravitational wave spectrum depending on the bubbles' wall velocity. Using holography, the wall velocity in a strongly coupled, non-Abelian, four-dimensional gauge theory is calculated from first principles. The dynamic determination of the wall velocity in relation to the nucleation temperature is verified, with ideal hydrodynamics providing an accurate description of the system except near the wall.
