Coherent control of an Helium-Ion ensemble
Saad Mehmood, Eva Lindroth, Luca Argenti
Attosecond pulses can ionize atoms in a coherent process. Since the emerging fragments are entangled, however, each preserves only a fraction of the initial coherence, thus limitin…

Control of the Ion Polarization in the Pump-Probe Ionization of Helium
Saad Mehmood, Eva Lindroth, Luca Argenti
Attosecond pump-probe ionization process can be used to prepare atomic ions in the coherent superposition of states with opposite parity. The multiphoton shake-up ionization of Hel…
