A recent paper, authored by V. Petrovic, H. Delibasic and I. Petrovic, presents an analytical model that investigates the impact of Coulomb effect on tunneling ionization events in an elliptically polarized laser field (Results in Physics 51 (2023) 106718). The model focuses on ionization rate and momenta, at a specific moment, based on recent experimental […]

Source: Max Planck Institute for Solid State Reseearch (https://www.fkf.mpg.de/8063969/2023_06_Garg)Can one see how atoms move inside a single molecule? By performing ultrafast spectroscopy in a scanning tunneling microscope, researchers from Max Planck Institute for Solid State Research (MPI-FKF Stuttgart) and Autonomous University of Madrid (UAM) showed that the periodic motion of the atoms (vibrations) in a single molecule […]

Modeling processes involving the promotion of an electrons to the continuum can be extremely challenging, since the asymptotic behavior of the continuum wave function is poorly described within correlated methods based on quadratically integrable finite basis sets (L2 basis sets), commonly used for bound states. Yet, beside an accurate description of the electron in the […]

Photoionisation time delays carry structural and dynamical information on the target system, including electronic correlation effects in atoms and molecules and electron transport properties at interfaces. In molecules, the electrostatic potential experienced by an outgoing electron depends on the emission direction, which should thus lead to anisotropic time delays. To isolate this effect, information on […]

Scientists from the Max Planck Institute Stuttgart, Universidad Autónoma de Madrid (UAM) and the IMDEA Nanoscience Institute have realized the first observation of electronic motion in real time and space. This advance represents the first step for the direct study of electronic dynamics in complex molecular systems without having to resort to complex image reconstruction […]

Heim, P; Mai, S; Thaler, B; Cesnik, S; Avagliano, D; Bella-Velidou, D; Ernst, WE; Gonzalez, L; Koch, M J. Phys. Chem. Lett. 11, 1443 (2020) The response of a molecule to photoexcitation is governed by the coupling of its electronic states. However, if the energetic spacing between the electronically excited states at the Franck−Condon window […]
