Metallic structures interacting with electromagnetic fields are known to exhibit properties similar to those found in atoms and molecules, such as multi-photon and tunnel ionization. Developing this similarity beyond the electron emission current, we generalize the wellknown Fowler-Nordheim model, and predict heretofore unrecognized source of nonlinear optical response from nano-structures exposed to illumination with intense optical pulses.

Universal long-wavelength nonlinear optical response of noble gases.
We demonstrate numerically that the long-wavelength nonlinear dipole moment and ionization rate versus electric field strength F for different noble gases can be scaled onto each other, revealing

TLDR
The quantum-corrected model (QCM), a novel approach that incorporates quantum-mechanical effects within a classical electrodynamic framework, is presented, opening a new venue for addressing quantum effects in realistic plasmonic systems.

TLDR
Measurements are presented that enable us to uniquely identify strong-field effects that are clearly resolved in the spectra of emitted electrons, showing that such a system may be ideal to extend strong- field studies from atomic gases to solid state systems.

Localized multiphoton emission of femtosecond electron pulses from metal nanotips.
TLDR
The strong optical nonlinearity of the electron emission allows us to image the local optical field near a metallic nanostructure with a spatial resolution of a few tens of nanometers in a novel tip-enhanced electron emission microscope.
