  2. 21. The Quest for M-theory

    Author : Ulf Gran; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; solitons; gauge symmetry; M-theory; string theory; duality; p-branes; D-branes; superspace; supergravity;

    Abstract : In ten dimensions, there exist five consistent string theories and in eleven dimensions there is a unique supergravity theory. When trying to find the fundamental theory of nature this is clearly an "embarrassment of riches". In the mid 90s, however, it was discovered that these theories are all related via a kind of transformation called duality. READ MORE

  4. 22. Aspects of Yang-Mills Theory : Solitons, Dualities and Spin Chains

    Author : Lisa Freyhult; Antti Niemi; Poul Damgaard; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical Physics; Field theory; String theory; Yang-Mills; Effective models; Supersymmetry; Solitons; Fermion number; Duality; AdS CFT correspondence; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

    Abstract : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. READ MORE

  5. 23. New horizons in string theory : bubble babble in search of darkness

    Author : Suvendu Giri; Ulf Danielsson; Bert Vercnocke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; black holes; dark energy; de Sitter; cosmological constant; M-theory; braneworld; anti de Sitter; Theoretical Physics; Teoretisk fysik;

    Abstract : It was discovered nearly two decades ago that we live in an accelerating universe that is dominated by dark energy. Understanding the origin of such an energy has turned out to be a very difficult open question in physics, and calls on the need for a fundamental theory like string theory. READ MORE

  6. 24. From Antagonism to Alienation : Redirecting Radical Democracy

    Author : Sofia Helander; Sofia Näsström; Bo Bengtsson; Alexandra Segerberg; Mikael Carleheden; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; political theory; social theory; democratic theory; critical theory; radical democracy; agonistic democracy; alienation; precarity; Statskunskap; Political Science;

    Abstract : How can democratic theory address contemporary problems of alienation? Today, alienation manifests itself primarily in processes of precarization and deprofessionalization. When the subject’s work security or professional autonomy is undermined, her relations – not only to others, but also to herself – can become inhibited. READ MORE

  7. 25. The Absent Meaning of Concrete Form in Theory of Architecture

    Author : Cecilia Häggström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; body; aesthetic theory; architecture; practical knowledge; artifacts; environmental theory; building function; architectural theory; phenomenology; aesthetic theory;

    Abstract : The aim of this dissertation is to discuss architecture as forming practical conditions for our way-of-being, and to clarify that which prevents traditional theory of architecture from dealing with these practical conditions as such. The dissertation investigates a theoretical problem concerning the nature of the relation between human being and the built environment. READ MORE
