The DBI Pseudo-Conformal Universe: Scale Invariance from Spontaneous Breaking of Conformal Symmetry
Speaker(s): Godfrey Miller
Abstract: The pseudo-conformal scenario is an alternative to inflation in which the early universe is approximately described by a conformal field theory in Minkowski space. Crucially, the cosmological background spontaneously breaks the flat space so(4,2) conformal algebra down to its so(4,1) de Sitter subal... read more

Spatially Covariant Theories of a Transverse, Traceless Graviton
Speaker(s): Godfrey Miller
Abstract: General relativity is a covariant theory of two transverse, traceless graviton degrees of freedom. According to a theorem of Hojman, Kuchar, and Teitelboim, modifications of general relativity must either introduce new degrees of freedom or violate the principle of general covariance. In my talk, I ... read more
