Graduate School - Dynamics in new Light
Material properties, phase transitions, and chemical modifications are ruled by elementary physical processes that take place within a few femtoseconds (1 fs = 10-15 s). Today these ultrafast timescales are accessible using optical techniques and are currently being pushed to the vacuum ultraviolet and X-ray regime.
In a solid, and at its surface, optical excitation allows us to drive the electronic subsystem almost instantaneously into a non-equilibrium state and follow its coupling to the lattice and
spin degrees of freedom. Thereby we can explore phase transformations, e.g., in spin-, charge- or
orbital-ordered systems. Moreover,
electrons are responsible for formation and breaking of chemical bonds via the manipulation of potential-energy landscapes that drive atomic motion. Here ultrashort VUV and X-ray pulses open the possibility to investigate photo-chemical processes with atomic spatial resolution and even beyond the Born-Oppenheimer limit.
The training program of DinL intends to improve education in the field of ultrafast X-ray science for PhD students who have a degree in physics, chemistry, or biology.
By bringing together groups who have recently combined research in XUV/X-ray HHG and plasma science with research efforts at FLASH, LCLS and BESSY II an effective channel is created for knowledge transfer between the laser community and the FEL/synchrotron-community.
Special training programs are designed to introduce our students to a broad range of instrumental techniques, instruct in scientific working, and teach general job skills. We intend to speed up the scientific career of young fellow researchers and thereby constitute the emerging field of time-resolved X-ray science in the Berlin
