1. Upholding the coral loop : Resilience, alternative stable states and feedbacks in coral reefs
Sammanfattning : Coral reefs are suffering unprecedented declines in coral cover and species diversity. These changes are often associated with substantial shifts in community structure to new dominant organisms. Ultimately, these “phase shifts” can be persistent and very difficult to return from.

2. Quantum Holonomy for Many-Body Systems and Quantum Computation
Sammanfattning : The research of this Ph. D. thesis is in the field of Quantum Computation and Quantum Information. A key problem in this field is the fragile nature of quantum states. LÄS MER
3. Geometrical Structure, Phase Diagrams, and Core-Level Binding Energiesof Metal Surfaces: Calculations, Simulations, and Experiments
Sammanfattning : This thesis concerns clean and adsorbate covered metal surfaces and surface alloys. These systems have been studied using theoretical and experimental methods. In the first part of the thesis, the different techniques that have been utilized in this work are presented, and the included publications are summarized. LÄS MER
4. Nonlinear Optical Materials Structural Studies of Alkali Titanium Phosphates
Sammanfattning : Crystals are beautiful, not only as pieces of jewellery, but also for their intrinsic properties, which are of significant scientific and technological importance. Ferroelectric materials are extremely versatile, since they may be combined with piezoelectric or electrooptic devices for use as filters, oscillators, memories, light detectors, and displays.
