The main aim of this project is to investigate the various ways in which language categorizes possession, how these are morphosyntactically encoded across and within languages, and how this distinction should be represented in a model of the language faculty.

In the field of Western art music, improvisation has become a much discussed topic. In this interdisciplinary study I argue that in this context, improvisation is not to be seen as a quasi-autonomous skill or art form, but as an aspect of music-making in general.

We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…
