Lightwave driven quantum dynamics: from molecular movies to Bloch waves

THE PRE-TALK FOR STUDENTS / AFTERNOON DISCUSSION SESSION WILL BE ANNOUNCED BY EMAIL. // Abstract: Electron recollision in an intense laser field gives rise to a variety of phenomena, ranging from electron diffraction to coherent soft X-ray emission. We have, over the years, developed intense sources of waveform-controlled mid-IR light to exploit the process with respect to ponderomotive scaling, quantum diffusion and quasi-static photoemission. I will describe how we leverage these aspects to 'teach' molecules to take a selfie while undergoing structural change. This permits visualizing for the first time, with combined attosecond temporal and atomic spatial resolution, molecular bond breaking and deprotonation. Furthermore, we achieve isolated attosecond pulses in the soft X-ray water window across the oxygen edge at 534 eV. Accomplishing ultrafast temporal resolution in combination with the soft X-ray's element specificity now provides an entirely new view on the combined electronic and nuclear dynamics in real time. I will show first results in which we resolve the carrier dynamics in a quantum material in real time and within the material's unit cell. These results provide first comprehensive insight into the dynamics of molecules and condensed matter, with the future possibility to address fundamental and long-standing questions such as molecular isomerization, phase transitions and superconductivity.

Titel:

Time Delay in Atomic and Molecular Photo-ionization

Modern laser techniques allow access to the ultrafast electron dynamics in atoms and molecules on the timescale of 10 to 100 attoseconds (1 as = 10-18 s). This development allowed to re-examine and re-evaluate decade old concepts of the Wigner time delay (1) and the tunneling time delay (2). The Wigner time delay is unambiguously established in atomic (3) and molecular (4) photoionization and serve as a useful tool to study both one-electron potentials and collective many-electron effects. The tunneling time delay is still the subject of a considerable debate and controversy (5). In this presentation, the story lines of the Wigner and tunneling time delays will be followed and illustrated by the most recent and significant experimental and theoretical results. (1) Eugene P.
