I will discuss how coherent electromagnetic radiation at Tera-Hertz frequencies can be used to drive complex solids periodically, controlling the coupling between their collective excitations.

These drives give rise to non-thermal states with unconventional types of microscopic order and new functional properties. Important examples involve the nonlinear control of the crystal lattice, used to induce magnetic order, ferroelectricity and non-equilibrium superconductivity at high temperatures.
