In this one-hour seminar, Andrea Cavalleri, Oxford University, will be presenting a talk titled:
“New Physics in Driven Quantum Materials”
Abstract – I will discuss how coherent electromagnetic radiation at Tera-Hertz and mid-infrared frequencies can be used to manipulate complex solids. As collective excitations are driven coherently and nonlinearly, new types of interactions in otherwise virtually uncoupled normal modes of the material are activated. These drives give rise to non-thermal states with unconventional properties, and sometimes with emergent order under a drive. Interesting examples involve the nonlinear control of the crystal lattice, used to induce magnetic order, ferroelectricity and non-equilibrium superconductivity at high temperatures.
Bio – Andrea Cavalleri is a founding director of the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg. He holds a laurea degree in Electrical Engineering from the University of Pavia (Italy) and held positions at the University of Essen (Germany), the University of California, San Diego and the Lawrence Berkeley National Laboratory (USA). In 2006, he became Professor of Physics at the University of Oxford. He joined the Max Planck Society in 2008. Professor Cavalleri is best known for his use of electromagnetic radiation to induce and study non-equilibrium phenomena in quantum solids. He has demonstrated that non-equilibrium superconductivity can be induced far above the thermodynamic transition temperature. He has been honored with the 2005 European Young Investigator Award (European Science Foundation), the 2015 Max Born Medal and Prize (German Physical Society, DPG and Institute of Physics, IOP), the 2015 Dannie Heineman Prize (Göttingen Academy of Science and Humanities) and the 2018 Isakson Prize (American Physical Society). Professor Cavalleri is a fellow of the American Physical Society, the AAAS and the British Institute of Physics (IOP) as well as an elected member of the Academia Europaea.
This seminar will take place in the ASRC auditorium while broadcast via Zoom.
