  1. 1. Cosmological implications of a QCD-like composite Higgs model

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Hristina Georgieva Hristova; [2021]
    Nyckelord :composite Higgs; technicolor; gravitational waves; LISA; phase transition; Physics and Astronomy;

    Sammanfattning : Some of the shortcomings of the Standard Model of particle physics are the 'unnatural' value of the mass of the Higgs boson and the fact that the model cannot account for the process of baryogenesis - a mechanism which generates the observed asymmetry between matter and anti-matter in the Universe. The former is related to the fundamental scalar nature of the Higgs boson, connected to quadratic divergences in the mass corrections. LÄS MER

  3. 2. Drakens son En objektstudie av en kinesisk skulptur på Röhsska Museet

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Charlotte Rudbeck; [2018-06-18]
    Nyckelord :Ceramic; Glaze; Sculpture; China; Dragon;

    Sammanfattning : This dissertation and object study focuses on a Chinese glazed ceramic sculpture at the Röhsska museum in Gothenburg, Sweden. The sculpture is supposed to be a part of the museum’s new Asian exhibition, at the museums reopening in the autumn of 2018. The sculpture is in need of cleaning before it is put into the new exhibition. LÄS MER

  4. 3. Development and Testing of the LOVES Spectrograph

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Petter Thorén; [2016]
    Nyckelord :Atomic Physics; Intrumentation; Spectroscopy; Spectrograph; UV; Ultra-Violet; Wavelengths; Vacuum; Echelle; Iron; Physics and Astronomy;

    Sammanfattning : In this report we present the testing and development made using the Lund Observatory Vacuum Echelle Spectrograph (LOVES) during the last few years. Hardware development includes an assembly from base components due to relocation and necessary calibrations of the optics. LÄS MER

  5. 4. Electrical Characterizationon Commercially Available Chemical Vapor Deposition (CVD) Graphene

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Mikael Anttila-Eriksson; [2016]
    Nyckelord :GFET; Graphene; Dirac point shift; Charge carrier mobility;

    Sammanfattning : Field-effect transistors (FET) based on graphene as channel has extraordinaryproperties in terms of charge mobility, charge carrier density etc. However, there aremany challenges to graphene based FET due to the fact graphene is a monolayer ofatoms in 2-dimentional space that is strongly influenced by the operating conditions.

  7. 5. Wheelsail- en landseglare på hjul

    Master-uppsats, Lunds universitet/Innovation

    Författare :David Brinkby; [2016]
    Nyckelord :Land sailing; Product development; Semcon; Outdoors activity; Technology and Engineering;

    Sammanfattning : This report describes the development of a land sailer together with the consulting company Semcon. The company wants to use the product at fairs and internal events, therefore shall the product reflect Semcons core values, which are “Responsibility, Credibility, Excellence”. LÄS MER
