  1. 1. Z2-Gauge Theory with Matter : Dispersive behaviour of a dimer in a 1+1-dimensional lattice

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Filip Ekblom; [2023]
    Nyckelord :Spin chain; Ising model; Dimer; Lattice; Lattice gauge theory;

    Sammanfattning : The intention with this thesis is to investigate a dimer in a spin chain. Inorder to do that, a model from Z2-gauge theory is taken as the theoretical motivation to construct a discrete lattice with Ising spin properties. A dimer is then allowed to exist indirectly in the empty space between sites. LÄS MER

    Sammanfattning : This bachelor thesis is written as a Minor Field Studies (MFS) project and funded by SIDA, Sweden’s International Development Cooperation Agency. The project was made in cooperation with Engineers Without Borders Sweden and the local organization Asulma Centre in Nairobi. LÄS MER

  4. 3. Phenomenological exploration of flavored Grand Unification through high-scale matching and renormalization group flow

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Hector Tiblom; [2023]
    Nyckelord :Grand Unification; GUT; trinification; spontaneous symmetry breaking; effective field theory; EFT; high-scale matching; renormalization group flow; Physics and Astronomy;

    Sammanfattning : The phenomenological success of the Standard Model (SM), and its unification of the electromagnetic and weak forces has inspired the search for a Grand Unified Theory (GUT), that dynamically reduces to the SM at low energies. In this work, we consider one such GUT, based on the trinification model [SU(3)]³ with an additional local SU(2) family symmetry, that is then broken directly to the gauge symmetry group of the SM.

  5. 4. Asymptotic Symmetries and Dressed States in QED and QCD

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Saimeng Zhou; [2023]
    Nyckelord :Dressed states; Large gauge transformation; Faddeev-Kulish formalism; Generalized coherent state operator; Wilson line; Infrared divergence; Asymptotic Hamiltonian; QED; QCD;

    Sammanfattning : Infrared divergences arising in theories with massless gauge bosons have been shown to cancel in scattering amplitudes when using dressed states constructed from the Faddeev- Kulish approach to the asymptotic states. It has been established that these states are closely related to asymptotic symmetries of the theory, that is, non-vanishing gauge trans- formations at the asymptotic boundary. LÄS MER

  7. 5. Graphic design, Already Intelligent? Current possibilities of generative AI applications in graphic design.

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Hampus Dehman; [2023]
    Nyckelord :Artificial Intelligence; Graphic Design; AI Art; Generative Artificial Intelligence; Process mapping; OpenAI; DALL-E; Chat-GPT;

    Sammanfattning : This paper analyzes the current possible implementations and limitations of generative AI applications such as Chat-GPT, DALL-E, and Midjourney. The applications were used in a specific scenario to gauge whether it was able to effectively handle a potential request from a client, the scenario was to create a visual identity for a shoe company called WalkWise.
