1. 1. Development of a guide system for free neutron oscillation searches at the European Spallation Source

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

   Author : Linnéa Björk; [2023]
   Keywords : ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

   Abstract : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

3. 2. Matter-streams as sources of the Kerr metric

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Julian Boy; [2022]
   Keywords : General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

   Abstract : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. READ MORE

4. 3. Searching for signatures of compositeness of the Higgs boson

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Mårten Bertenstam; [2021]
   Keywords : two-Higgs-doublet model; composite Higgs model; composite two-Higgs-doublet model; phase transition; cosmological phase transition; electroweak phase transition; gravitational waves; gravitational wave background; Physics and Astronomy;

   Abstract : In this master thesis we consider some phenomenological aspects of two-Higgs-doublet models, both elementary and composite ones. The emphasis is on calculating and understanding first order phase transitions in such models, constrained to be in agreement with existing collider data on the Higgs sector. READ MORE

5. 4. Centrifugal Turbopumps - Flow Physics and Modelling

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Carl Eriksson; Hampus Henåker; [2021]
   Keywords : Centrifugal Pumps; Rocket Science; Turbopumps; Two-Zone Model; Impeller; Vaneless Diffuser; Vaned Diffuser; Technology and Engineering;

   Abstract : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. READ MORE

6. 5. Galactic Dynamics and the spread of Galactic Civilisations

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Markus Strickert; [2020]
   Keywords : Physics and Astronomy;

   Abstract : Abstract The idea of the spread of life through the galaxy is, in most minds, considered science fiction. Yet, scientists argue that most galaxies have had more than enough time for civilisation development and space travel. READ MORE
