Graviton oscillations in the two-brane world
Andrei Barvinsky, Alexander Kamenshchik, Claus Kiefer +1
We study the braneworld effective action in the two-brane Randall-Sundrum model. In the framework of this essentially-nonlocal action we reveal the origin of an infinite sequence o…
Discrete Spectra of Charged Black Holes
Andrei Barvinsky, Saurya Das, Gabor Kunstatter
Bekenstein proposed that the spectrum of horizon area of quantized black holes must be discrete and uniformly spaced. We examine this proposal in the context of spherically symmetr…
Nonlocal braneworld action: an alternative to Kaluza-Klein description
Andrei Barvinsky, Alexander Kamenshchik, Andreas Rathke +1
We construct the nonlocal braneworld action in the two-brane Randall-Sundrum model in a holographic setup alternative to Kaluza-Klein description: the action is written as a functi…
New nonlocal effective action
A. O. Barvinsky, V. F. Mukhanov
We suggest a new method for the calculation of the nonlocal part of the effective action. It is based on resummation of perturbation series for the heat kernel and its functional t…
