Thanks to their collective nature, superradiant electronic excitations in solid state systems can couple very efficiently with light, allowing to reach the so-called ultrastrong coupling regime. I will present two systems in which such regime has been observed using a two dimensional electron gas coupled to a terahertz resonator. I will show how the ultrastrong coupling regime allows the observation of new physics, most remarkably quantum vacuum phenomena closely related to the dynamical Casimir effect.
