High-harmonic generation in Fibonacci quasicrystals — •Francisco Navarrete and Dieter Bauer — Institut für Physik, Universität Rostock, 18051 Rostock, Deutschland

The mechanism of high-harmonic generation (HHG) in solids has been theoretically studied over recent years, and experimentally verified a decade ago. While many conclusions have been drawn for this process in periodic crystals, it has also been predicted a strong dependence of the HHG spectrum on the topology of the sample. The latter motivated us to explore the strong-field response of quasicrystals (QCs), which are solids whose atoms are geometrically placed in ways that are symmetrically forbidden in periodic crystals (which are comparatively abundant and have been vastly studied). This might provide insight on fundamental questions of its electron dynamics and allow us to explore the suitability to use them for compact short-wavelength light sources. Even though in our study we focus on a simplified model for QCs, the Fibonacci chain, these conclusions might also be extrapolated to both synthesized and natural QCs.
