In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

This thesis mainly extends the theory of positive operators on Riesz spaces to a setting of pre-Riesz spaces.

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…

Eike Kiltz (thans als postdoc in dienst van het MI) heeft samen met zijn coauteurs David Cash, Dennis Hofheinz en Chris Peikert de "EUROCRYPT 2010 Best Paper Award" ontvangen voor hun articel "Bonsai Trees, or How to Delegate a Lattice Basis".

To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

What happens to electrical waves that have to cross gaps in insulation material around nerves in the human body

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

If X is a locally compact Hausdorff space, then a representation of the complex C* algebra C_0(X) on a Hilbert space $H$ is given by a spectral measure that takes its values in the orthogonal projections on $H$.

Nepnieuws over ‘patiënt zero’ en ronkende koppen zoals ‘het gele gevaar’. Leidse wetenschappers spotten wereldwijd veel valse berichten over het coronavirus en discriminerende stereotypering van Chinezen. Hoe schadelijk is dat?

Een nieuwe NMR-microscoop geeft natuurkundigen een verbeterd instrument om fundamentele fysische processen te onderzoeken. Het biedt ook nieuwe mogelijkheden voor de medische wetenschap, bijvoorbeeld om eiwitten beter te bestuderen in de hersenen van Alzheimerpatiënten. Publicatie in Physical Review…
