Photoelectron interferometry with spectrally shaped polychromatic infrared pulses
E. A. Boati, G. Arvidsson, M. Ammitzböll +19
Laser-assisted photoelectron interferometry is a cornerstone of attosecond science, first used to characterize attosecond pulse trains and later to study photoionization dynamics.…
Probing Wigner time delays with photoelectron interferometry: Anisotropic long-range imprint of the short-range centrifugal potential
Morgan Berkane, Camille Lévêque, Richard Taïeb +2
We consider the two-photon ionization of Hydrogen-like atoms. We find an approximate expression of the long-range phase based on an asymptotic expansion of the continuum eigenfunct…
Vibronic correlations in molecular strong field dynamics
Marie Labeye, Camille Lévêque, François Risoud +3
We investigate ultrafast vibronic dynamics triggered by intense femtosecond infrared pulses in small molecules. Our study is based on numerical simulations performed with 2D model…
Ultrafast Nuclear Dynamics in Double-Core Ionized Water Molecules
Iyas Ismail, Ludger Inhester, Tatiana Marchenko +30
Double-core-hole (DCH) states in isolated water and heavy water molecules, resulting from the sequential absorption of two x-ray photons, have been investigated. A comparison of th…
Anisotropic molecular photoemission dynamics: Interpreting and accounting for the nuclear motion
Antoine Desrier, Morgan Berkane, Camille Lévêque +2
We investigate how vibration affects molecular photoemission dynamics, through simulations on two-dimension asymmetric model molecules including the electronic and nuclear motions…
Anisotropic Molecular Photoemission Dynamics Part. I Wigner meets the RABBIT
Berkane M., Desrier A., Lévêque C. +2
We investigate signatures of anisotropy on the dynamics of time-resolved near-threshold molecular photoemission, through simulations on a one-dimension asymmetric model molecule. M…
Laser Excitation of the 1S-2S Transition in Singly-Ionized Helium
Elmer L. Gründeman, Vincent Barbé, Andrés Martínez de Velasco +6
Precision laser spectroscopy in the extreme ultraviolet of the 1S-2S two-photon transition in singly-ionized helium is a promising route for tests of fundamental physics. We demons…
Strong-field photoionization by circularly polarized light
Jonathan Dubois, Camille Lévêque, Jérémie Caillat +3
We demonstrate that strong-field ionization of atoms driven by circularly polarized light becomes an adiabatic process when described in the frame rotating with the laser field. As…

K. Lévêque-Simon, A. Camper, R. Taïeb +3
We present cross sections for the formation of positronium chloride (PsCl) in its ground state from the charge exchange between positronium (Ps) and chloride (Cl) in the range…
Phase-resolved attosecond near-threshold photoionization of molecular nitrogen
S. Haessler, B. Fabre, J. Higuet +10
We photoionize nitrogen molecules with a train of extreme ultraviolet attosecond pulses together with a weak infrared field. We measure the phase of the two-color two-photon ioniza…
Specific chemical bond relaxation unravelled by analysis of shake-up satellites in the oxygen single site double core hole spectrum of CO
Anthony Ferté, Francis Penent, Jérôme Palaudoux +7
We developed recently [A. Ferté, et al., J. Phys. Chem. Lett. 11, 4359 (2020)] a method to compute single site double core hole (ssDCH or K) spectra. We refer to that method…
Photoionization of chiral molecules by counter-rotating bicircular laser fields: a chiral attoclock
Samuel Beaulieu, Sylvain Larroque, Antoine Comby +6
Measuring and controlling the ionization dynamics by intense laser fields has recently led to important breakthroughs, from the investigation of tunneling time delays to attosecond…
Attosecond dynamics through a Fano resonance: Monitoring the birth of a photoelectron
