A particular emphasis is placed on processes which—due to the localized excitation in optical near-fields—exhibit different properties and scalings from their counterparts in the gas phase or at planar surfaces. The Chapter is structured in two parts. The first part discusses various regimes in highly nonlinear photoelectron emission from metallic nanotips, including field-driven photoemission at near- and mid-infrared frequencies, and the control of localized photoemission using intense terahertz transients. In the second part, multiphoton and strong-field ionization of atomic gases in plasmonic antennas and waveguides is presented. It is demonstrated that local ionization is enabled by optical field enhancements in various types of structures. At the same time, fundamental physical limitations preventing efficient high-harmonic generation in nanostructures are discussed."],["dc.identifier.doi","10.1007/978-3-319-20173-3_10"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62693"],["dc.language.iso","en"],["dc.publisher","Springer"],["dc.relation.isbn","978-3-319-20172-6"],["dc.relation.isbn","978-3-319-20173-3"],["dc.relation.ispartof","Ultrafast Dynamics Driven by Intense Light Pulses"],["dc.relation.issn","1615-5653"],["dc.relation.issn","2197-6791"],["dc.title","Highly Nonlinear and Ultrafast Optical Phenomena in Metallic Nanostructures"],["dc.type","book_chapter"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
