    • Magnus expansion method for two-level atom interacting with few-cycle pulse 

      T.Begzjava; J.S.Ben-Benjamina; R.Nesslera; Eleuch, Hichem (Taylor & Francis, 2017-07-14)
      Using the Magnus expansion to the fourth order, we obtain analytic expressions for the atomic state of a two-level system driven by a laser pulse of arbitrary shape with small pulse area. We also determine the limitation ...
