Phys. Rev. Lett. 94, 093002 (2005) [4 pages]Nonsequential Double Ionization as a Completely Classical Photoelectric EffectReceived 21 September 2004; published 9 March 2005 We introduce a unified and simplified theory of atomic double ionization. Our results show that at high laser intensities (I≥1014 W/cm2) purely classical correlation is strong enough to account for all of the main features observed in experiments to date. © 2005 The American Physical Society URL:
