1. Flow of charged particles in Pb-Pb and pp collisions at the LHC
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. LÄS MER
2. The Inflationary Universe
Kandidat-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : Astrophysical observations of the cosmic microwave background point to inconsistencies in the standard model of cosmology, and a primordial accelerated expansion of the universe known as inflation has been suggested as a solution. Unfortunately, observational evidence of inflation is lacking, and there exists hundreds of models that populate the inflationary landscape. LÄS MER
3. Quantum Gauge Fields in Cosmology: Cosmic Inflation and Gravitational Waves
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : In this thesis, the consequences of introducing Yang-Mills fields into cosmology are investigated. This is done by the effective action approach, in which the coupling constant is allowed to depend on the quantum fields. LÄS MER
4. Gravitational Waves in Bimetric Gravity
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : Understanding the cause of the accelerated expansion of the Universe is one of the most pressing issues in modern cosmology. An alternative to the LambdaCDM-model is bimetric gravity which is an extension of Einstein's theory of general relativity. LÄS MER
5. Assessing the relationship between hypoxia and life on Earth, and implications for the search for habitable exoplanets
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Atmospheric oxygen at the level of present-day Earth (21%) is generally regarded as permissive for the development and survival of complex multicellular life, such as animals. The hypothesis that oxic conditions are conducive for multicellular life has subsequently been applied to the search for life elsewhere in the universe, with planets exhibiting atmospheric oxygen of a similar level to Earth being considered as candidates for habitability.
