In this talk, I will discuss how coherent electromagnetic radiation at TeraHerz frequencies can be used to coherently rearrange atoms within the crystal lattice of a solid. I will especially report on a number of recent experiments in which such coherent modulation has been used to induce a mysterious non-equilibrium superconducting state at temperatures far in excess of the thermodynamic transition point Tc. I will also discuss how femtosecond x-ray beams from free electron lasers are integral to these studies, and are used to image structures during these non-equilibrium processes.
