I will discuss how coherent electromagnetic radiation at TeraHertz frequencies can be used to drive complex solids periodically, creating non-thermal states with unconventional types of microscopic order and new functional properties. Important examples involve the nonlinear control of the crystal lattice, to induce atomic-structural deformations often not possible in equilibrium, and used by our group to induce interesting collective states at high temperatures, including magnetic order, ferroelectricity and non-equilibrium superconductivity.
