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…

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…
