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

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

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

    Sammanfattning : 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. Expansions of neutrino oscillation and decay probabilities in matter

    Master-uppsats, KTH/Fysik

    Författare :Jesper Grönroos; [2023]
    Nyckelord :Theoretical physics; Particle physics; Neutrino physics; Neutrino oscillations; Series expansions; Physics beyond the Standard Model; Teoretisk fysik; Partikelfysik; Neutrinofysik; Neutrinooscillationer; Serieutvecklingar; Fysik bortom Standardmodellen;

    Sammanfattning : We consider a simple model for invisible neutrino decay as a sub-leading effect in the standard three-flavor neutrino oscillation framework, and use the Cayley–Hamilton formalism to obtain a full set of neutrino oscillation probabilities in matter. These are given as analytical series expansions in the small parameters α ∼ O(λ^2) and s_13 ∼ O(λ), where λ ≡ 0. LÄS MER

  4. 3. The Application of a TCSC Controller to Improve the Stability of a Power System With High Penetration of Renewable Energy

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Albin Wanhainen; Axel Gomér; [2023]
    Nyckelord :;

    Sammanfattning : The goal of this project is to examine how a higher penetration of power electronics-basedforms of power production affects system stability and damping. The project covers howpower system stability can be improved by using a Thyristor Controlled Series Capacitor(TCSC) with Power Oscillation Damping (POD). LÄS MER

  5. 4. Quantum Transport in Topological Insulator Nanowires

    Master-uppsats, KTH/Fysik

    Författare :Sergi Pradas Rodriguez; [2023]
    Nyckelord :quantum transport; topological insulators; nanowires; numerical analysis; Kwant; etc.; kvanttransport; topologiska isolatorer; nanotrådar; numerisk analys; Kvant; etc.;

    Sammanfattning : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. LÄS MER

  7. 5. Development and Application of Analytical Tools for Calcium Signaling Dynamics in MDCK-II Cells

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Hanna Israelsson; [2023]
    Nyckelord :Cellpose 2.0; MDCKII; GCaMP6m; Gap Junctions; Calcium; Ouabain; Cellpose 2.0; MDCKII; GCaMP6m; Gap Junctions; Kalcium; Ouabain;

    Sammanfattning : Calcium, a pivotal ion in various human signaling pathways, holds significant relevance in cancer research and treatment. Investigating the transmission of spontaneous calcium signals between cells and understanding how they are influenced by different treatments is therefore an interesting area of study. LÄS MER
