  1. 1. F-theory on six-dimensional symmetric toroidal orbifolds

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Finn Bjarne Kohl; [2021]
    Nyckelord :F-theory; orbifolds; String Theory; String Phenomenology; roto-translations; six-dimensional; F-Theorie; Orbifaltigkeiten; String Theorie; String Phenomenologie; Roto-Translationen; sechs-dimensional;

    Sammanfattning : In this thesis, compactifications of F-theory on six dimensional symmetric toroidalorbifolds are explored. These orbifold geometries have been mathematically classified and it is natural to ask what the physical implications of string theorycompactifications on those geometries are. LÄS MER

  3. 2. Modeling of RF Heating in the JET Tokamak

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

    Författare :Emil Söderman; Wilhelm Holmberg; [2021]
    Nyckelord :fusion; tokamak; ICRH; RF heating; JET;

    Sammanfattning : Fusion reactors need methods to couple externalpower to confined plasmas. Ion cyclotron resonance heating(ICRH) is a method to radiate electromagnetic waves to couplepower to the kinetic motion of gyrating ions in a plasma. In thisreport we study ICRH with regard to the dispersive effects ofthe confined plasma in the JET tokamak. LÄS MER

  4. 3. Study of Kinematic Variables in Multi-Lepton Final States in search for an Exotic Higgs Boson

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Axel Gallén; [2021]
    Nyckelord :LHC; ATLAS; CERN; Standard Model; Higgs boson; Exotic Higgs boson; Kinematic variables; Physics and Astronomy;

    Sammanfattning : The Large Hadron Collider in Geneva was constructed as a discovery machine. So far, the Higgs boson has been the only discovery at the Large Hadron Collider, but physicists keep on pushing the limit in order to discover new particles. LÄS MER

  5. 4. Investigation of the magnetic fields of a young Sun-like star ∏1 UMa

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Lawen Ahmedi; [2020]
    Nyckelord :Magnetic field; star; young Sun; polarisation; Stokes vector;

    Sammanfattning : In astronomy, the Sun has an important role. It keeps the solar-system together and is thesource for life, heat, light and energy to Earth. As any other star or planet, the Sun has amagnetic field. The magnetic field of the Sun has a great impact on the Sun itself as well asits surrounding. LÄS MER

  7. 5. Steady ideal flows with vorticity in toroidal domains and periodic cylinders

    Master-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Gustav Jillbratt; [2020]
    Nyckelord :Partial differential equations; Euler equation; Vorticity; Fluid dynamics; Mathematics and Statistics;

    Sammanfattning : In a paper from 1970, Lortz constructs rotational solutions to the steady Euler equation in toroidal domains using a fixed point method. We shall review this method and rewrite it using Banach's fixed point theorem. LÄS MER
