In this talk, I will discuss some our recent work aimed at controlling the properties of high Tc cuprates with light. Especially innovative is our focus on driving excitations at THz frequencies beyond their linear response regime, exploring new regimes in the manipulation of emergent properties.
I will cover our recent work on the light enhancement of coherence in the bilayer cuprate YBa2Cu3O6+x, in which spectacular enhancement of coherence below Tc is observed, accompanied by possible transient superconductivity above Tc.
I will discuss the combination of THz control also with Ultrafast X-ray probing, as achieved at Free Electron Lasers.
Bio: As a faculty member at the University of Oxford, Prof. Cavalleri is leading a small group of students and postdocs in the application of high intensity THz radiation to induce phase transitions in complex oxides, especially controlling the transition between insulating and metallic states in manganites and between striped and superconducting phases in High-Tc cuprates. He was also the initiator of the Time Resolved ARPES beamline at the Rutherford Appleton Laboratory, for which he secured funding, collaborated at the design and developed the first scientific applications. Cavalleri’s also group worked closely with Sarnjeet Dhesi at the Diamond Light Source, co-developing time resolved capabilities at the nanoscience beamline (I06).
In July 2008 Andrea Cavalleri became a Professor of Physics at the University of Hamburg, and was the first director of the Max Planck Research Department for Structural Dynamics. Between 2008 and 2013, he built a new research group engaged in experiments that range from nonlinear THz methods to time resolved ARPES. Cavalleri’s group is also a frequent user of the LCLS Free Electron Laser (Stanford), the FELBE THz Free Electron Laser (Dresden) and the Diamond Light Source (Oxfordshire).
Since 2013, Cavalleri has been serving as founder and managing director of the Max Planck Institute for the Structure and Dynamics of Matter.
