B01.00003: Ultrafast strong field AMO Physics Invited Speaker: Philip Bucksbaum Quantum Electron-electron and electron-ion dynamics drive all processes in molecular physics, yet for many years these elemental motions were difficult to capture in experiments because of the ultra-short time scales and distances involved. Two advances in laser technology have enabled ultrafast imaging and ultrafast quantum control of molecules. The first was the development 30 years ago of powerful ultrafast lasers with focused optical fields comparable to the binding fields in chemical bonds, exceeding one volt per Angstrom. These lasers led to new ways to control the the interactions of electrons in atoms on their natural time scales. The second advance was the development in the last decade of ultrafast x-ray lasers with Angstrom-wavelengths and even higher focused fields. X-ray laser diffraction from molecular gases can be used to produce movies of molecules undergoing bond re-arrangements in tens to hundreds of femtoseconds. Recent improvements in the x-ray source will soon enable measurements that can resolve attosecond-scale electron motion in x-ray-atom interactions. [Preview Abstract] |

B01.00004: STIRAP: some news and notes about its history Invited Speaker: Klaas Bergmann Ever since its introduction (see J. Chem. Phys. 92, 5363, 1990), STIRAP -- a method for population transfer between quantum states with unprecedented efficiency and robustness -- has enjoyed an amazing development and wide spread application, far beyond initial expectations. In a first part a small selection of some important or surprising successful applications of STIRAP will be mentioned, including e.g. ultra-cold molecule formation, STIRAP\textasciiacute s role in precision experiments or controlling the propagation of light or even acoustic waves. Although STIRAP could have been found accidentally, it was the result of a planned approach. Therefore, a second part will show the line of development, starting some 50 years ago, that led eventually to STIRAP in a step-by-step approach, including -- as an intermediate -- the development of exotic devices such as an optically pumped laser with a molecular beam being the active medium.

B01.00005: Free Electrons and Molecules -- a Lifelong Passion Invited Speaker: Michael Allan I shall present a personal retrospective of a few highlights of my nearly life-long fascination with encounters of free electrons with atoms and molecules. With a modest number of graduate students, we built electron spectrometers which permitted us to measure in hitherto inaccessible regions in terms of low energies, higher resolution, higher sensitivity and low background, scattering angles extending to 0$^\circ$ and 180$^\circ$. The infrastructure was continually improved and was used to look into many aspects of the intricate inner life of resonances and how they make physical and chemical changes happen. Collaborations with a number of theoretical groups were of decisive importance in the entire enterprise. The highlights will include: \begin{itemize} \item Electronic excitation of atoms and molecules. \item Nonlocal and threshold effects. \item How do two-dimensional electron-energy loss spectra reveal nuclear dynamics of negative ion resonances. \end{itemize} [Preview Abstract] |
