Roadmap on Attosecond Science
Rocio Borrego Varillas, Pierre Agostini, Fernando Ardana-Lamas +108
Twenty-five years have passed since the first experimental demonstration of attosecond pulses, marking the advent of our ability to resolve and control electron motion in real time…
Coherent vibrational dynamics in molecular bond breaking: methyl radical umbrella mode probed by femtosecond x-ray spectroscopy
Christian A. Schröder, John H. Hack, Joshua L. Edwards +6
We report on the observation of coherent molecular vibrations launched by the breaking of a molecular bond. The methyl radical, which is produced by photodissoci…
All-optical logic gates for extreme ultraviolet switching via attosecond four-wave mixing
Patrick Rupprecht, Daniel M. Neumark, Stephen R. Leone
All-optical logic-gate-based switching is a prerequisite for photonic computing. This article introduces a logic-gate protocol for noncollinear four-wave mixing (FWM) of one attose…
Probing autoionization decay lifetimes of the core-excited states in xenon using attosecond noncollinear four-wave-mixing spectroscopy
Nicolette G. Puskar, Patrick Rupprecht, Jan DvoÅák +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…
Tracing long-lived atomic coherences generated via molecular conical intersections
Patrick Rupprecht, Francesco Montorsi, Lei Xu +7
Accessing coherences is key to fully understand and control ultrafast dynamics of complex quantum systems like molecules. Most photochemical processes are mediated by conical inter…
