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
Bridging quantum and classical plasmonics with a quantum-corrected model.
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.

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.
High-order-harmonic generation by enhanced plasmonic near-fields in metal nanoparticles
We present theoretical investigations of high-order harmonic generation (HHG) resulting from the interaction of noble gases with localized surface plasmons. These plasmonic fields are produced when a
Localized multiphoton emission of femtosecond electron pulses from metal nanotips.
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.
Attosecond physics in photoemission from a metal nanotip
Nanometre-scale metal tips irradiated by femtosecond laser pulses represent ultrafast electron sources. The combination of the laser pulse and the tip offers the possibility of extending attosecond

Enhanced harmonic generation in gases using an all-dielectric metasurface
Abstract Strong field confinement, long-lifetime resonances, and slow-light effects suggest that metasurfaces are a promising tool for nonlinear optical applications. These nanostructured devices
