Modes of log gravity

Year: 2011

Type: article

Abstract: The physical modes of a recently proposed $D$-dimensional ``critical gravity'', linearized about its anti-de Sitter vacuum, are investigated. All ``log mode'' solutions, which we categorize as ``spin-2'' or ``Proca'', arise as limits of the massive spin-2 modes of the noncritical theory. The linearized Einstein tensor of a spin-2 log mode is itself a `nongauge' solution of the linearized Einstein equations whereas the linearized Einstein tensor of a Proca mode takes the form of a linearized general coordinate transformation. Our results suggest the existence of a holographically dual logarithmic conformal field theory.
