  1. 552. (I) Conformal Field Theory in Embedding Space
    Jean-Francois Fortin (Laval University)
    09/06/2021, 12:45
    Theoretical Physics / Physique théorique (DTP-DPT)
    Invited Speaker / Conférencier(ère) invité(e)

    We develop the embedding space formalism and determine the full operator product expansion relevant to conformal field theories in arbitrary spacetime dimensions. With the operator product expansion, we then show how to compute generic conformal blocks for correlation functions with any number of quasi-primary operators in arbitrary irreducible representations of the Lorentz group. ...

  2. 51. (I) Holographic Complexity in Gravitational Collapse
    Andrew Frey (University of Winnipeg)
    09/06/2021, 12:50
    Theoretical Physics / Physique théorique (DTP-DPT)
    Invited Speaker / Conférencier(ère) invité(e)

    Through the AdS/CFT correspondence, properties of a quantum field theory are equivalent to geometric quantities in the bulk of anti-de Sitter spacetime. The complexity of the QFT state at some time is conjectured to be either the volume of a slice through AdS or the action on a patch of AdS. We evaluate both types of complexity during the gravitational collapse of a scalar field in AdS, which...

  3. 82. Quantum field theory with minimum length
    Vasil Todorinov (University of Lethbreidge)
    09/06/2021, 12:55
    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral (Non-Student) / Orale (non-étudiant(e))

    Theories of Quantum Gravity predict a minimum measurable length and a corresponding modification of the Heisenberg Uncertainty Principle to the so-called Generalized Uncertainty Principle (GUP). However, this modification is non-relativistic, making it unclear whether the minimum length is Lorentz invariant. We formulate a Relativistic Generalized Uncertainty Principle, resulting ...

  4. 202. (G*) Numerical Loop-Integration Methods for Thermal Field Theory
    Siyuan Li (University of Saskatchewan)
    09/06/2021, 12:58
    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    The basic structure of quantum field theory that is used to describe the Standard Model of fundamental interactions of nature is usually formulated for zero temperature. However, the effects of temperature are extremely important for understanding a number of physical processes such as the electro-weak phase transition and quark-gluon plasma. Thermal field theory is the extension of quantum...

  5. 438. Bandlimited UDW detector dynamics on 2+1 flat and spherical spacetimes
    Ahmed Shalabi (University of Waterloo)
    09/06/2021, 13:01
    Theoretical Physics / Physique théorique (DTP-DPT)
    Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

    The potential breakdown of the notion of a metric at high energy scales could imply the existence of a fundamental minimal length scale below which distances cannot be resolved. One approach to realizing this minimum length scale is construct a quantum field theory with a bandlimit on the field. We report on an investigation of the effects of imposing a field bandlimit on a curved and compact...
