  1. 1852. The Inflation Phenomenology of Primordial Phonons, Gravitons, Isocons, and Dilatons with the CMB and LSS, past, present and future

    Invited Speaker / Conférencier invité

    CMB and LSS allow us to probe the relics of inflation: phonons aka spatial volume fluctuations, which combine into an entropy-like measure, the orthogonal though entangled isocons, the holy grail gravitons, and the 4-volume dilaton fluctuations. The Standard Model of Cosmology is an amazing few parameter characterization of Planck and other data, but our theorizing and CMB + LSS experiments...

  2. 1573. Coleman-Weinberg mechanism in a gravitational Weyl invariant theory

    We consider a massless conformally (Weyl) invariant classical action consisting
    of a magnetic monopole coupled to gravity in an anti-de Sitter background spacetime. We implement quantum corrections and this breaks the conformal (Weyl) symmetry, introduces a length scale via the process of renormalization and leads to the trace anomaly. We calculate the one-loop effective potential and...

  3. 1563. Black holes and wormholes subject to conformal mappings
    Prof. Valerio Faraoni (Bishop's University)

    CLOSED - Oral (Non-Student) / orale (non-étudiant)

    Analytic solutions of the field equations of scalar-tensor gravity can look very different in different conformal frame representations. For example, certain Brans class IV solutions describing wormholes in the Jordan frame correspond to horizonless geometries in the Einstein frame. The reasons for such a change of behaviour under conformal mappings are elucidated in general.
