Applications are invited for one postdoc and two PhD positions in the group of Hans Jakob Wörner at ETH Zürich ( www.atto.ethz.ch <http://www.atto.ethz.ch> ). This project aims at developing attosecond transient-absorption spectroscopy of molecules at photon energies ranging up to 500 eV (or 2.5 nm wavelength). This energy range gives access to the K-shell absorption edges of several elements including carbon and nitrogen which makes element-specific measurement of electronic wave packets possible. Experiments will be carried out both on molecules in the gas phase and on solvated molecules in liquid microjets. Presently initiated experiments are based on 2-cycle laser pulses centered at 1.8 microns at 1kHz repetition rate and address both field-free and field-driven electronic dynamics in gas-phase molecules. Future experiments will make use of a 50 W-average power few-cycle mid-IR laser system that is presently under development. Applications will be reviewed starting immediately and until the positions are filled. ----------------------------------------------------------- Prof. Dr. Hans Jakob Wörner Laboratorium für physikalische Chemie ETH Zürich Vladimir-Prelog-Weg 2 8093 Zürich Switzerland Web: www.atto.ethz.ch <http://www.atto.ethz.ch/> Email: [log in to unmask] Tel.: +41 44 633 44 12 Fax: +41 44 632 15 38 ----------------------------------------------------------- To join or leave the molecular-dynamics-news email list, go to: http://www.jiscmail.ac.uk/lists/molecular-dynamics-news.html
