Query: Coherent Control of the Non-instantaneous Nonlinear Power-law Response
  in Resonant Nanostructures   We experimentally demonstrate coherent control of the nonlinear response of
optical second harmonic generation in resonant nanostructures beyond the
weak-field regime. Contrary to common perception, we show that maximizing the
intensity of the pulse does not yield the strongest nonlinear power-law
response. We show this effect emerges from the temporally asymmetric
photo-induced response in a resonant mediated non-instantaneous interaction. We
develop a novel theoretical approach which captures the photoinduced
nonlinearities in resonant nanostructures beyond the two photon description and
give an intuitive picture to the observed non-instantaneous phenomena.
