1. Svenska gymnasieelevers uppfattningar om storlek och avstånd i universum
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för utbildningsvetenskapSammanfattning : This study aims to investigate how students in Swedish upper secondary school conceptualize sizes and distances of some astronomical objects, such as planets and stars, as well as the students’ general knowledge of the objects themselves. The study uses a constructivist framework and explores how well the students’ conceptions match the scientific facts and definitions, and what misconceptions and alternative conceptions they hold.

2. Phase Transitions in the Two-Higgs-Doublet Model with a Softly-Broken Z2 Symmetry
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : The two-Higgs-doublet model (2HDM) is an extension to the Standard Model which adds a second Higgs doublet. This extension provides freedom within the model, in comparison to the Standard Model, which makes it possible to study strong electroweak phase transitions. LÄS MER
3. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. LÄS MER
4. Hybrid Microwave Resonator-Nanoscale Conductor Systems
Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. LÄS MER
5. Non-Diffractive Nuclear Excitations In Angantyr
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. LÄS MER
