Abstract
For a finite-sized generic nanostructured band gap material, it is shown that significant laser-induced correlation effects can be introduced by a two-color pump-probe scheme where edge states are resonantly pre-excited by the pump before the probe arrives and drives the generation of high-order harmonics. Compared with the response of a bulk sample, we demonstrate an increase in the efficiency of the generated high-harmonic signal over a wide range of frequencies by harnessing the power of these ultrafast many-electron dynamics.
