Driven Quantum Materials
I will discuss how coherent electromagnetic radiation at infrared and TeraHertz frequencies can be used to drive collective excitations nonlinearly and manipulate complex solids. Important examples involve the nonlinear control of the crystal lattice, to induce atomic-structural deformations often not possible in equilibrium. Structural control through nonlinear phononics, has been used by our group to induce interesting collective states at high temperatures, including magnetic order, ferroelectricity, topological phenomena and non-equilibrium superconductivity.
