  2. 21. Topics in Five Dimensional Supersymmetry and Topological Quantum Field Theories

    Author : Luigi Tizzano; Maxim Zabzine; Anton Kapustin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmetric Quantum Field Theories; Topological Quantum Field Theories; String Theory.;

    Abstract : We explore five-dimensional supersymmetric quantum field theories and topological quantum field theories. In five dimensions, we describe a framework to consistently define a supersymmetric theory on a curved spacetime manifold. READ MORE

  4. 22. Emergent spacetime from simple field theories

    Author : Julius Engelsöy; Bo Sundborg; Sumit R. Das; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AdS CFT; thermalization; quench; large N singlet models; emergent spacetime; fysik; Physics;

    Abstract : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a black hole in the bulk spacetime is dual to a thermal state in the boundary CFT, thermalization in the CFT is dual to black hole formation in AdS. READ MORE

  5. 23. Quenched coupling and thermal behavior in the O(N) vector model

    Author : Julius Engelsöy; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Abstract : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a thermal state in the boundary CFT is dual to a black hole in the bulk spacetime, thermalization in the CFT is dual to black hole formation in AdS. READ MORE

  6. 24. Abelian Extensions, Fractional Loop Group and Quantum Fields

    Author : Pedram Hekmati; Jouko Mickelsson; Christoph Schweigert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lie group extensions; Lie conformal algebras; gerbes; twisted K-theory; renormalization; anomalies; D-brane charges; variational complex; Mathematical physics; Matematisk fysik;

    Abstract : This thesis deals with the theory of Lie group extensions, Lie conformal algebras and twisted K-theory, in the context of quantum physics. These structures allow for a mathematically precise description of certain aspects of interacting quantum field theories. READ MORE

  7. 25. Direct RF sampling receivers for wireless systems in CMOS technology

    Author : Darius Jakonis; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The fast development of wireless communication systems asks for more flexible and more cost-effective radio architectures. A long term goal is a software defined radio, where communication standards are chosen by reconfiguration of hardware. READ MORE
