DESCRIPTION:Prof. Andrea Cavalleri\, Max Planck Institute & Oxford Univers
 ity\nIn this talk\, I will discuss some our recent work aimed at controlli
 ng the properties of high Tc cuprates with light. Especially innovative is
  our focus on driving excitations at THz frequencies beyond their linear r
 esponse regime\, exploring new regimes in the manipulation of emergent pro
 perties.\nI will cover our recent work on the light enhancement of coheren
 ce in the bilayer cuprate YBa2Cu3O6+x\, in which spectacular enhancement o
 f coherence below Tc is observed\, accompanied by possible transient super
 conductivity above Tc.\nI will discuss the combination of THz control also
  with Ultrafast X-ray probing\, as achieved at Free Electron Lasers.\nBio:
  As a faculty member at the University of Oxford\, Prof. Cavalleri is lead
 ing a small group of students and postdocs in the application of high inte
 nsity THz radiation to induce phase transitions in complex oxides\, especi
 ally controlling the transition between insulating and metallic states in 
 manganites and between striped and superconducting phases in High-Tc cupra
 tes. He was also the initiator of the Time Resolved ARPES beamline at the 
 Rutherford Appleton Laboratory\, for which he secured funding\, collaborat
 ed at the design and developed the first scientific applications. Cavaller
 i’s also group worked closely with Sarnjeet Dhesi at the Diamond Light S
 ource\, co-developing time resolved capabilities at the nanoscience beamli
 ne (I06).\nIn July 2008 Andrea Cavalleri became a Professor of Physics at 
 the University of Hamburg\, and was the first director of the Max Planck R
 esearch Department for Structural Dynamics. Between 2008 and 2013\, he bui
 lt a new research group engaged in experiments that range from nonlinear T
 Hz methods to time resolved ARPES. Cavalleri’s group is also a frequent 
 user of the LCLS Free Electron Laser (Stanford)\, the FELBE THz Free Elect
 ron Laser (Dresden) and the Diamond Light Source (Oxfordshire).\nSince 201
 3\, Cavalleri has been serving as founder and managing director of the Max
  Planck Institute for the Structure and Dynamics of Matter.
