  1. 1. Spins and Giants : Fundamental Excitations in Weakly and  Strongly Coupled ABJM Theory

    Författare :Olof Ohlsson Sax; Joseph A. Minahan; Gianluca Grignani; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; AdS CFT correspondence; Integrable field theory; Mathematical physics; Matematisk fysik; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The discovery of integrability on both sides of the duality between planar N=4 super Yang-Mills theory and free type IIB string theory in AdS5 × S5 has lead to great progress in our understanding of the AdS/CFT correspondence. Similar integrable structures also appear in the more recent three-dimensional superconformal N=6 Chern-Simons-matter theory constructed by Aharony, Bergman, Jafferis and Maldacena (ABJM), as well as in its gravity dual, type IIA string theory on AdS4 × CP3.

  3. 2. "Hallen var lyst i helig frid" : Krig och fred mellan gudar och jättar i en fornnordisk hallmiljö

    Författare :Tommy Kuusela; Olof Sundqvist; Terry Adrian Gunnell; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Giants; Old Norse; Religion; Halls; Old Norse Religion; Mythology; Óðinn; Þórr; History of Religion; religionshistoria;

    Sammanfattning : This thesis is the first study to examine the interaction between gods and giants in Old Norse mythology from the perspective of Iron Age halls. Its central aim is to contextualise Old Norse mythological narratives that describe the interactions between gods and giants in a hall environment, and to show how the mythological depictions can be compared to the norms and rules found in Iron Age hall culture, especially in connection with its warrior ideology.

  4. 3. Interacting Giants and Compact Stars

    Författare :Alexey Bobrick; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stars Binaries: General; stars : neutron; stars : subdwarfs; stars : supergiants; hydrodynamics; nuclear reactions; nucleosynthesis; abundances; stars Binaries: General; stars : neutron; stars : subdwarfs; stars : supergiants; hydrodynamics; nuclear reactions; nucleosynthesis; abundances; Fysicumarkivet A:2021:Bobrick;

    Sammanfattning : This thesis is based on four papers dealing with various aspects of interactions in binary stars. Interactions between stars occur at nearly all stages of their evolution and can take many forms. LÄS MER

  5. 4. Stellar Winds of Cool Giants : Investigating the Mass-Loss Mechanism of AGB Stars

    Författare :Sofie Liljegren; Susanne Höfner; Kjell Eriksson; Bernd Freytag; Hans Olofsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; late-type stars; AGB stars; stellar winds; stellar atmospheres; dust; stellar pulsation; hydrodynamics; radiative transfer;

    Sammanfattning : Asymptotic giant branch (AGB) stars are luminous cool giants of low to intermediate mass that are strongly pulsating and non-spherical, with heavy mass loss through a stellar wind. The mass loss makes these stars important for galactic chemistry, as the wind enriches the interstellar medium with new elements and dust, and it determines the final fate of these stars. LÄS MER
