Abstract
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.

Speaker. Our research group is active in the general area of time-evolving phenomena of solids. We work on experimental methods to drive materials out of equilibrium, often using Terahertz or mid infrared pulses derived from femtosecond lasers. These phenomena are interrogated with ultrafast optical, x-ray or electrical probes, generated on tabletops or using X-Ray Free Electron Lasers.
