Summary

The course will cover fundamental concepts and recent developments in the field of ultrafast spectroscopy and introduce the basic theory to understand ultrafast (10-16 - 10-9 s) phenomena in chemistry, biology and condensed matter physics.

Content

For the study of electronic and structural dynamics in solids and (bio-) molecules in ¿real¿ time, a variety of time-resolved spectroscopic techniques (in the optical, THz, and X-ray region of the electromagnetic spectrum, as well as using short electron pulses) are available.¿The fastest dynamics that are accessible with state-of-the-art experiments are the motion of electrons in the attosecond regime (10-18-10-16 s), vibrational motion of molecules (10-14 s), and electronic relaxation pathways (>10-12 s). Examples include the breaking of interatomic bonds, vibrational dynamics in molecular systems, tracking of radiative and non-radiative electron relaxation pathways in biological systems, as well as charge carriers dynamics in materials.¿The course addresses technological and theoretical aspects, and in the last part a few examples from literature will be studied:

1. Principles of femtosecond laser system

2. Time-resolved spectroscopy methods

3. Theory (no, or minimal, pre-existing knowledge is required)

4. Examples: Photon-Echo spectroscopy, Biological electron an energy transfer, Solvation dynamics, charge carriers in materials, etc.¿¿

Students are encouraged to bring up subjects/papers for discussion.
