  1. 21. Exact Results in Five-Dimensional Gauge Theories : On Supersymmetry, Localization and Matrix Models

    Författare :Anton Nedelin; Joseph Minahan; Ivan Kostov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetric localization; Matrix Models; Chern-Simons theory; Supersymmetric Field Theories; 2; 0 theories; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : Gauge theories are one of the corner stones of modern theoretical physics. They describe the nature of all fundamental interactions and have been applied in multiple branches of physics. The most challenging problem of gauge theories, which has not been solved yet, is their strong coupling dynamics. LÄS MER

  3. 22. Strings, boundary fermions and coincident D-branes

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

    Sammanfattning : 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.

  4. 23. Non-conformal gauge/string duality : A rigorous case study

    Författare :Xinyi Chen-Lin; Konstantin Zarembo; Jorge Russo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AdS CFT correspondence; holographic principle; supersymmetric localization; Wilson Loops; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The gauge/string duality, a.k.a. the holographic principle is a profound assertion that emerged from string theory. LÄS MER

  5. 24. Mathematical Foundations of Equivariant Neural Networks

    Författare :Jimmy Aronsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; symmetry; geometric deep learning; gauge theory; induced representations; fiber bundles; convolutional neural networks; equivariance;

    Sammanfattning : Deep learning has revolutionized industry and academic research. Over the past decade, neural networks have been used to solve a multitude of previously unsolved problems and to significantly improve the state of the art on other tasks. However, training a neural network typically requires large amounts of data and computational resources. LÄS MER

  7. 25. Twisting it up the Quantum Way : On Matrix Models, q-deformations and Supersymmetric Gauge Theories

    Författare :Rebecca Lodin; Maxim Zabzine; Taro Kimura; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matrix models; Virasoro constraints; Virasoro algebra; W algebra; q-deformations; Supersymmetric gauge theories; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The mathematical framework which quantum field theory constitutes has been very successful in describing nature. As an extension of such a framework, the idea of supersymmetry was introduced. This greatly simplified the mathematical description of the theories, making them more tractable. LÄS MER
