Description
Friction and noise naturally emerge when gravitational waves propagate through unknown environments. In this talk, I will present a framework that extends effective field theories to systematically incorporate these effects. I will show how fundamental principles — such as symmetries, locality, and unitarity —place constraints on the form of dissipation and noise. Finally, I will discuss the phenomenological consequences for the tensor sector of the early universe, emphasizing potential observational signatures of these effects.
