  1. 1. 2d Gauge Theories

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Zhou Zheng; [2022]
    Nyckelord :;

    Sammanfattning : The Yang-Mills gauge theories play prominent role in modern high energy physics and the direct non-perturbative calculations present the main challenge in the field.Two dimensional gauge theories provide a nice playground where it is possible to carry out exact computations and at the same time some non-trivial phenomena canbe studied.

  3. 2. Cosmological Implications of the Quantum SU(2) Yang-Mills Fields

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

    Författare :Emil Boman; [2019]
    Nyckelord :Cosmic Inflation; Yang-Mills; SU 2 gauge fields; Physics and Astronomy;

    Sammanfattning : We study the key properties of the quantum SU(2) Yang-Mills ground state and its possible role in the early Universe, in particular, as a driver of Cosmic Inflation. Using the effective action approach and separating the Yang-Mills field potential into homogeneous (condensate) and inhomogeneous (fluctuations) components, we reproduce the conformal-time solutions for the two different types of the Yang-Mills condensate in the minimum of the effective Lagrangian for generic initial conditions.

  4. 3. Selected topics in the phonology and morphosyntaxof Laboya : A field study

    Master-uppsats, Stockholms universitet/Institutionen för lingvistik

    Författare :Allahverdi Verdizade; [2019]
    Nyckelord :Austronesian languages; Indonesia; Sumba; Laboya; Lamboya; clitics; Austronesiska språk; Indonesien; Sumba; Laboja; Lamboja; klitikor; Bahasa Austronesia; Indonesia; Sumba; Lamboya; Laboya; klitik;

    Sammanfattning : The present study investigates selected topics in the phonology and morpho-syntax of Laboya, a largely undescribed Austronesian language of Sumba island in eastern Indonesia. The study was carried out during nine weeks of field work. The language data is comprised by collected questionnaires and free narratives. LÄS MER

  5. 4. Driver behavior impact on pedestrians' crossing experience in the conditionally autonomous driving context

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Su Yang; [2017]
    Nyckelord :Autonomous vehicle; pedestrian s experience; conditionally autonomous driving;

    Sammanfattning : Autonomous vehicles are developing at a rapid pace while pedestrians' experience with autonomous vehicles is less researched. This paper reported an exploratory study where 40 participants encountered a conditionally autonomous vehicle with unusual driver behaviors at crossing by watching videos and photos. LÄS MER

  7. 5. Yang-Mills driven Cosmic Expansion

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

    Författare :Jimmy Ljungberg; [2016]
    Nyckelord :Cosmic Inflation; Dark Energy; Yang-Mills; SU 2 gauge fields; Perturbations; Physics and Astronomy;

    Sammanfattning : This thesis will investigate the possibility to have SU(2) gauge fields as the source to the Cosmic Inflation and/or to the Dark Energy. It will be explained that, under certain conditions, the Universe can be filled with vector fields without violating its isotropy. Those conditions are naturally fulfilled within the SU(2) gauge theory. LÄS MER
