Nanolocalized nonlinear electron photoemission under coherent control

We theoretically show that two-photon coherent control yields electron photoemission from metal nanostructures localized in nano-size hot spots whose positions are controllable on nanometer scale, in agreement with recent experiments. We propose to use silver V-shapes as tailored nanoantennas for which the position of the coherently-controllable photoelectron-emission hot spot can be deterministically predicted. We predict that low-frequency, high-intensity excitation of the photoemission leads to exponentially high contrast of the coherent control.
