Sommario/riassunto

This thesis presents significant advances in the imaging and theory of the ultrafast dynamics of surface plasmon polariton fields. The author details construction of a sub-10 femtosecond and sub-10 nanometer spatiotemporal resolution ultrafast photoemission microscope which is subsequently used for the discovery of topological meron and skyrmion-like plasmonic quasiparticles. In particular, this enabled the



creation of movies of the surface plasmon polariton fields evolving on sub-optical wavelength scales at around 0.1 femtosecond per image frame undergoing vortex phase evolution. The key insight that the transverse spin of surface plasmon polaritons undergoes a texturing into meron or skyrmion-like topological quasiparticles (defined by the geometric charge of the preparation) follows. In addition, this thesis develops an analytical theory of these new topological quasiparticles, opening new avenues of research, while the ultrafast microscopy techniques established within will also be broadly applicable to studies of nanoscale optical excitations in electronic materials.

Sommario/riassunto

This book provides the first sustained critical exploration, and celebration, of the relationship between Geography and the contemporary Visual Arts. With the growth of research in the Geohumanities and the Spatial Humanities, there is an imperative to extend and deepen considerations of the form and import of geography-art relations. Such reflections are increasingly important as geography-art intersections come to encompass not only relationships built through interpretation, but also those built through shared practices, wherein geographers work as and with artists, curators and other creat
