Simultaneous double ionization of C60 molecules in single-cycle pulses

We theoretically investigate simultaneous double ionization of C60 Buckminsterfullerene clusters within the strong field approximation, taking into account two-body effects like Coulomb blocking. Our analysis suggests that for infrared single-cycle pulses, simultaneous double ionization becomes comparable in magnitude to sequential double ionization. Additionally, estimates show that Coulomb blocking weakens with increasing cluster size and field strength.Studienstiftung des Deutschen Volkeshttps://doi.org/10.13039/501100004350Peer Reviewe
