Of particular interest is the strong coupling regime of cavity-QED, where the light-matter coupling strength exceeds the decay rates [6,7]. In this case, light and matter can exchange energy in a (quasi) reversible way and the eigenstates, called polaritons, feature an hybrid character with shifted frequencies. After having introduced different types of excitations that can be strongly coupled to the vacuum field in condensed-matter systems, I will discuss recent results showing a modification of superconductivity under strong light-matter coupling conditions .
