Description
I review recent developments concerning the use of nonperturbative renormalization group techniques for describing the nontrivial infrared regime of light scalar fields in de Sitter space. Long wavelength fluctuations (in units of the spacetime curvature) undergo a dramatic gravitational amplification which is responsible for dramatic phenomena, such as the radiative restoration of spontaneously broken symmetries.
