Joint Photon Sciences Institute (JPSI) Seminar

"Ultrafast optical control in complex materials"

Presented by Raanan (Ron) Tobey, University of Oxford, United Kingdom

Tuesday, June 2, 2009, 1:30 pm — NSLS Seminar Room, Bldg. 725, Room 2-125

The macroscopic electronic phases of strongly correlated materials are known to be extremely susceptible to external stimuli. Early studies explored the effects of magnetic field, chemical and externally applied pressure on the emergent properties. Likewise, exposure of these materials to radiation has shown to be an effective method of controlling their properties. In this talk I will discuss the application of ultrafast optical techniques to study the non-equilibrium dynamics during laser-induced phase transitions. I will highlight methods which allow us to excite specific internal degrees of freedom and monitor the sample evolution along multiple reaction coordinates.
