Will LIGO see RIGO's? - Radion-induced graviton oscillations in the two-brane world
Andrei O. Barvinsky, Alexander Yu. Kamenshchik, Claus Kiefer +1
One of the most interesting features of braneworld models is the existence of massive gravitational modes in addition to the usual massless one. Mixing of the modes which depends n…
Mass Spectrum for Black Holes in Generic 2-D Dilaton Gravity
A. Barvinsky, G. Kunstatter
Two arguments for the quantization of entropy for black holes in generic 2-D dilaton gravity are summarized. The first argument is based on reduced quantization of the only physica…
Conformal Decomposition of the Effective Action and Covariant Curvature Expansion
A. O. Barvinsky, A. G. Mirzabekian, V. V. Zhytnikov
The class of effective actions exactly reproducing the conformal anomaly in 4D is considered. It is demonstrated that the freedom within this class can be fixed by the choice of th…
Heat Kernel and Loop Currents by the Generating Function Method
Andrei Barvinsky, Yuri Gusev
The generating function method is applied to the trace of the heat kernel and the one-loop effective action derived from the covariant perturbation theory. The basis of curvature i…
