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...
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...
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.
