Title: Gravitational waves from phase transitions with holography
With the advent of gravitational wave (GW) astronomy a new door into learning about properties of matter has been opened. In particular, gravitational waves coming from a first order phase transitions are expected to be detectable by next generation experiments. These are assumed to proceed via the nucleation, expansion and collision of bubbles. An accurate prediction of the spectrum implies computing out-of-equilibrium properties of quantum field theories, which are challenging even at weak coupling. This offers a golden opportunity for holography to make an impact on astrophysics and cosmology. In this talk I will review recent progress in the context of cosmological phase transitions, including a possible alternative mechanism of GW emission, and neutron star mergers.
