  2. 11. Linear response theory : from black hole thermalization to Weyl semimetals

    Author : Jorge Laraña Aragón; Bo Sundborg; Edwin Langman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. READ MORE

  4. 12. Phenomenology of Inert Scalar and Supersymmetric Dark Matter

    Author : Erik Lundström; Joakim Edsjö; Lars Bergström; Michel Tytgat; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dark matter; inert scalars; supersymmetry; indirect detection; accelerator searches; Physics; Fysik; Astroparticle physics; Astropartikelfysik; Elementary particle physics; Elementarpartikelfysik; teoretisk fysik; Theoretical Physics;

    Abstract : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. READ MORE

  5. 13. Topological excitations in field theory models of superconductivity and magnetism

    Author : Philipp Rybakov; Egor Babaev; Maxim Mostovoy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Teoretisk fysik; Theoretical Physics;

    Abstract : Topological excitations are subjects of intensive studies in physics and mathematics. In solid-state and soft matter physics, topological excitations can largely determine the thermodynamic and electromagnetic properties of materials, while in high energy physics they were theorized as particles.

  6. 14. Form and function of complex networks

    Author : Petter Holme; Beom Jun Kim; Mark Newman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; complex networks; complexity; small-world networks; scale-free networks; graph theory; Teoretisk fysik; Physics; Fysik; teoretisk fysik; Theoretical Physics;

    Abstract : Networks are all around us, all the time. From the biochemistry of our cells to the web of friendships across the planet. From the circuitry of modern electronics to chains of historical events. A network is the result of the forces that shaped it. READ MORE

  7. 15. Theoretical studies of X-ray induced nuclear dynamics

    Author : Ivaylo Minkov; Hans Ågren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Teoretisk fysik; Physics; Fysik;

    Abstract : The present thesis is a theoretical study of several x-ray spectroscopies { x-ray absorption, xray photoelectron, radiative and non-radiative resonant Raman scattering spectroscopy. The main focus point is investigating the role of the nuclear dynamics in molecules (naphthalene, biphenyl, the water dimer, HCl) on these spectra. READ MORE
