In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

LCD-schermen gebruiken vloeibare kristallen die weliswaar een vloeistof vormen maar toch in hoge mate geordend zijn. Een nieuwe theorie brengt nu het samenspel in kaart tussen orde, temperatuur en symmetrie. Publicatie in Physical Review X.

Financiële markten en hun gedrag: de kranten staan er bol van. Je kunt je afvragen of er voor een natuurkundige interessante aspecten te ontdekken zijn. Econofysica houdt zich sinds kort met dit soort vragen bezig. In maart 2011 start dr. Diego Garlaschelli in Leiden als tenure-track assistant-professor…
