CFN Virtual Colloquium

"Driven Quantum Materials"

Presented by Prof. Andrea Cavalleri, Condensed Matter Department, Max Planck Institute for the Structure and Dynamics of Matter, Center for Free-Electron Laser Science (CFEL), Department of Physics, University of Oxford, Clarendon Laboratory, Germany

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.
