Nonlinear optical excitation of a two-level system with a superoscillating field — •Daniel Berghoff, Matthias Reichelt und Torsten Meier — Department of Physics and CeOPP, University of Paderborn, Warburger Str. 100, D-33098 Paderborn, Germany

Although superoscillations are a well known phenomena [1], the impact on a nonlinearly photoexcited two-level system (TLS) was only recently investigated by Baranov et al. [2]. Here, the excitation with different electric fields is studied. Among other things we show that the TLS can be excited by off-resonant superoscillations. Furthermore, parameters are numerically obtained, for which a maximum population inversion is observed.
