    Invited Speaker / Conférencier invité
    I will explain how the large-scale cosmological dynamics can be obtained from the hydrodynamics of condensate states of quantum gravity (to be specific, isotropic group field theory condensate states in the Gross-Pitaevskii approximation). The correct Friedmann equations are recovered in the semi-classical limit for appropriate choices of the parameters in the action for the group field...

  2. 1020. Basic elements of loop quantum gravity
    Jonathan Ziprick
    14/06/2016, 16:45
    Theoretical Physics / Physique théorique (DTP-DPT)
    Invited Speaker / Conférencier invité
    The main idea of loop quantum gravity (LQG) is to develop a canonical quantum theory of general relativity (GR). In this talk, I will give a pedagogical account of LQG aimed at physicists who are unfamiliar with the field. The main focus will be on basic elements of the construction and how these relate to more familiar objects in GR and quantum field theory.

    From the EPR paper in 1935, to Bell’s theorem in the 1960s, to Aspect’s EPR experiment in the 1980s and its recent refinements demonstrating km range correlations, it has become increasingly clear that entangled quantum mechanical systems are inherently nonlocal. EPR experiments highlight the theoretical divergence between quantum mechanics (QM) as a theory of matter in need of a theory of...
