Nano-scale electronic structure of strongly correlated electron systems
In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

Postmaterialism and Socioeconomic Status Impact in the Chilean Voting Behavior
This paper describes the development process of voting behavior in Chile; particularly the relationship between the class voting theory and the theory of cultural post-materialist vote is investigated. This research deals with Chile as a case study, a developing country with a relatively stable democracy…

Growth-induced self-organization in bacterial colonies
Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

Scattering and absorption in 2D optics
Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium
Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Robots die zich inleven in de mens
Om intelligentere en liefst ook sociale robots en computersystemen te bouwen, moet er eerst meer kennis komen over de manier waarop mensen informatie interpreteren. Max van Duijn en Tessa Verhoef doen onderzoek op het snijvlak tussen sociale wetenschap en AI.

Noisy Patterns: Bridging the gap between stochastics and dynamics
In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…
