  2. 1. Vacua in String Theory : de Sitter Space and Stability in Flux Compactifications

    Author : Sergio C. Vargas; Ulf Danielsson; Alessandro Tomasiello; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; Cosmology; Flux Compactifications; Landscape; Swampland;

    Abstract : Our understanding of cosmology has evolved radically in the last decades. Current models demand the presence of dark energy in our universe and the most favored candidate behind this component is a small positive cosmological constant that characterizes a de Sitter (dS) spacetime.

  4. 2. Cosmoparticle Physics and String Theory

    Author : Stefan Sjörs; Marcus Berg; Joseph Conlon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; dark matter; cosmology; inflation; modifications of gravity; string theory; flux compactifications; perturbative string theory; teoretisk fysik; Theoretical Physics;

    Abstract : This thesis deals with phenomenological and theoretical aspects of cosmoparticle physics and string theory. There are many open questions in these topics. In connection with cosmology we would like to understand the detailed properties of dark matter, dark energy, generation of primordial perturbations, etc. READ MORE

  6. 4. Light scattering and absorption in pigmented coatings : Theory and experiments

    Author : William E. Vargas; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : Radiative transfer models are used to describe optical properties of polymericthick films containing spherical inhomogeneities with sizes comparable to thewavelength of the incident radiation. From Lorenz-Mie theory various parametersrelated to elastic light scattering and absorption by single particles are calculated, i.e. READ MORE

  7. 5. Extensions in Flux : An Essay on Vagueness and Context Sensitivity

    Author : Jonas Åkerman; Peter Pagin; Diana Raffman; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; vagueness; context sensitivity; contextualism; weak tolerance; sorites paradox; forced march; equivocation; indexicals; Fara; Raffman; Shapiro; Soames; Theoretical philosophy; Teoretisk filosofi; Theoretical Philosophy; teoretisk filosofi;

    Abstract : The extensions of vague predicates like ‘is bald’, ‘is tall’, and ‘is a heap’ apparently lack sharp boundaries, and this makes such predicates susceptible to soritical reasoning, i.e. reasoning that leads to some version of the notorious sorites paradox. READ MORE
