On the measurability of Wigner time delays at shape resonances in photodetachment of polyatomic anions
Jan Dvořák, Jakub Benda, Thomas N. Rescigno +3
The energy dependence of the complex phases of electron continuum wave functions carries information about electron dynamics. Streaking and attosecond interference experiments (cal…
Probing autoionization decay lifetimes of the core-excited states in xenon using attosecond noncollinear four-wave-mixing spectroscopy
Nicolette G. Puskar, Patrick Rupprecht, Jan Dvořák +6
The decay of core-excited states is a sensitive probe of autoionization dynamics and correlation effects in many-electron systems, occurring on the fastest timescales. Xenon, with…
Isotope-Selective Strong Field Ionization of Semi-Heavy Water
Andrew J. Howard, M. Britton, Zachary L. Streeter +4
Semi-heavy water (HOD) is one of the simplest molecules in which the bonds are labelled by isotope. We demonstrate that a pair of intense few-femtosecond infrared laser pulses can…
Attosecond X-ray Core-level Chronoscopy of Aromatic Molecules
Jia-Bao Ji, Zhaoheng Guo, Taran Driver +32
Attosecond photoemission or photoionization delays are a unique probe of the structure and the electronic dynamics of matter. However, spectral congestion and spatial delocalizatio…
Two-electron interference in two-photon attosecond double ionization of neon
Siddhartha Chattopadhyay, Carlos Marante, Barry I. Schneider +2
The pump-probe experiments enabled by X-ray free-electron lasers (XFEL) will allow us to directly observe correlated electronic motion with attosecond time resolution by detecting…
