  2. 1. Strings, boundary fermions and coincident D-branes

    Author : Linus Wulff; Ulf Lindström; Fawad Hassan; Dmitri Sorokin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; string theory; open strings; D-branes; supersymmetry; non-abelian gauge theory; tensionless strings; Physics; Fysik;

    Abstract : The appearance in string theory of higher-dimensional objects known as D-branes has been a source of much of the interesting developements in the subject during the past ten years. A very interesting phenomenon occurs when several of these D-branes are made to coincide: The abelian gauge theory living on each brane is enhanced to a non-abelian gauge theory living on the stack of coincident branes.

  6. 4. Tensionless Strings and Supersymmetric Sigma Models : Aspects of the Target Space Geometry

    Author : Andreas Bredthauer; Ulf G. Lindström; Bengt E.W. Nilsson; Uppsala universitet; []
    Keywords : Theoretical physics; Theoretical Physics; String Theory; Tensionless Strings; Supergravity Backgrounds; Plane Wave; Supersymmetry; Non-linear Sigma Models; Generalized Complex Geometry; Teoretisk fysik;

    Abstract : In this thesis, two aspects of string theory are discussed, tensionless strings and supersymmetric sigma models.The equivalent to a massless particle in string theory is a tensionless string. Even almost 30 years after it was first mentioned, it is still quite poorly understood. READ MORE

  7. 5. Stroke Darkly the Strings : On Paul Celan and Music

    Author : Axel Englund; Anders Olsson; Jacob Derkert; Martin Zenck; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Paul Celan; music; poetry; intermediality; metaphor; modernism; Jörg Birkenkötter; Harrison Birtwistle; György Kurtág; Erhard Karkoschka; Tilo Medek; Aribert Reimann; Wolfgang Rihm; Peter Ruzicka; Literature; Litteraturvetenskap; Literature; litteraturvetenskap;

    Abstract : The aim of this study is to disclose the oeuvre of the German-Romanian Holocaust survivor Paul Celan as a site of problematic yet productive encounters between poetry and music. It addresses, on the one hand, music as a thematic and structural element in Celan’s poetry and, on the other hand, contemporary musical works interacting with this poetry. READ MORE
