Direct visualization of electronic states in photoexcited crystals

Luca PERFETTI, Laboratoire des Solides Irradiés UMR Ecole Polytechnique-CNRS

The recent developments of femtosecond photon sources in the ultraviolet spectral range have largely enriched the techniques to probe condensed matter on ultrafast timescales. Among the possible (...)

Interstellar PAHs : a challenge for molecular physicists

Christine Joblin, IRAP, Université de Toulouse (UPS-OMP), CNRS

Polycyclic aromatic hydrocarbons (PAHs) have been proposed to be an ubiquitous component of cosmic matter. Interstellar PAHs absorb UV photons from stars and reemit the energy in the Aromatic (...)

Local Density Friction and Surface Hopping Studies of Non-adiabatic Effects at Molecular Scattering from Metal Surfaces

Alexander Kandratsenka Department of Dynamics at Surfaces Max-Planck-Institut für biophysikalische Chemie, Göttingen

Séminaire commun LCAR-LCPQ
Recent experimental studies of atomic (H) an molecular (NO) scattering from metal (Au) surfaces show unambiguously the important role of non-adiabatic effects in energy (...)

UN INTERFEROMETRE A ATOMES PIEGES POUR LA MESURE DE FORCES A FAIBLE DISTANCE

FRANCK PEREIRA DOS SANTOS, LNE-SYRTE, OBSERVATOIRE DE PARIS, LNE, CNRS, UPMC, 61 AVENUE DE L’OBSERVATOIRE, 75014 PARIS, FRANCE

Je présenterai l’état d’avancement d’un projet qui vise à réaliser, à l’aide de techniques d’interférométrie atomique, des mesures de forces à faible distance, entre des atomes de Rb et un miroir (...)
