Phase transitions in rich dark sectors
Deadline: 05/02/2026
Scientific-Disciplinary Group
02 - Physics
Description
The research project will focus on particle physics and fundamental interactions and in particular on rich dark sectors, i.e., extensions of the SM below the electroweak scale with weak couplings to visible particles (thus "dark") with a rich structure, with multiple particles and interactions, in the context of the ERC DarkSHunt project. In these cases, the breaking of dark symmetry can generate gravitational waves when such a phase transition is of the first order. If it is supercooled, it could also explain the recent discovery of a stochastic background of gravitational waves from PTA experiments. The project will study the theoretical aspects of phase transitions by analyzing them from an analytical and numerical viewpoint, with the ELENA code, and considering the subsequent production of gravitational waves. It will compare the results with those of NanoGrav and other PTA experiments and the sensitivities of future experiments such as SKA.
