6. Optical Spectroscopy on Correlated Electron Materials
Sammanfattning : Strongly correlated materials poses a great challenge to our microscopic understanding of matter, mainly due to the inability of perturbative methods to predict the properties of such materials. This inability stems from strong correlations between electronic, lattice and spin degrees of freedom, leading to a variety of complex and exotic phenomena such as (unconventional) superconductivity, metal-insulator transitions, non-Fermi liquid behavior and colossal magnetoresistance.

Sammanfattning : The overall aim of this thesis is to explore freedom of speech and aspects of credibility related to the Internet. The phenomenon freedom of speech is seen and examined principally from a communicative perspective. Theoretically the thesis is based on three key concepts: Internet, freedom of speech, and credibility. LÄS MER
9. On Aggregation and Dynamics of Opinions in Complex Networks
Sammanfattning : This thesis studies two problems defined on complex networks, of which the first explores a conceivable extension of structural balance theory and the other concerns convergence issues in opinion dynamics. In the first half of the thesis we discuss possible definitions of structural balance conditions in a network with preference orderings as node attributes. LÄS MER
10. The Internet in China. Unlocking and Containing the Public Sphere
Sammanfattning : The aim of this dissertation is to address a paradox: government control and social freedom on China's Internet are growing simultaneously. The study, which is based on fieldwork conducted between 2002 and 2006, and 48 interviews, seeks answers to the following two questions: 1. LÄS MER
