1. Correlation Functions in Integrable Theories : From weak to strong coupling
Sammanfattning : The discovery of integrability in planar N=4 super Yang-Mills and ABJM has enabled a precise study of AdS/CFT. In the past decade integrability has been successfully applied to the spectrum of anomalous dimensions, which can now be obtained at any value of the coupling. LÄS MER
2. Finite Element Procedures for Fluid-structure Interaction
Sammanfattning : This thesis concerns finite element (FE) methods for solving fluid-structure interaction (FSI) problems. Two types of fluid-structure interaction are considered. A finite element method for solving the interaction between a flowing incompressible fluid and a linear elastic structure is proposed. The flow is assumed to be laminar. LÄS MER
3. Ion escape from Mars : measurements in the present to understand the past
Sammanfattning : Present-day Mars is a cold and dry planet with a thin CO2-dominated atmosphere comprising only a few mbar pressure at low altitudes. However, the Martian surface is marked with valley networks, hydrated mineral clays, carbonates and the remains of deltas and meandering rivers, i.e. LÄS MER
4. Quantum Materials Probed by Light and Electron Spectroscopy
Sammanfattning : As new technologies rely heavily on materials’ properties, the quest for novel tunable electronic and magnetic materials occupies a large part of nowadays research efforts. Most promising materials are quantum materials, which exhibit a wide range of exotic electronic and magnetic phenomena and often show a great sensitivity to external perturbations such as temperature, pressure or chemical doping.

5. Strong Light-Matter Coupling: the Road from Conventional to Cavity-Free Polaritons
Sammanfattning : The interaction between light and matter is fundamental in perceiving and understanding the world. The interaction is typically weak, meaning light only perturbs matter without changing its properties. LÄS MER
