Holography, The Second Law and a C̃-Function in Higher Curvature Gravity
We analyze the Second Law of black hole mechanics and the generalization of the holographic bound for general theories of gravity. We argue that both the possibility of defining a holographic bound and the existence of a Second Law seem to imply each other via the existence of a certain “c-function” (i.e. a never-decreasing function along outgoing null geodesic flow). We are able to define such...
متن کاملLocalized Gravity and Higher Curvature Terms
We consider localization of gravity in smooth domain wall solutions of gravity coupled to a scalar field with a generic potential in the presence of the Gauss-Bonnet term. We discuss conditions on the scalar potential such that domain wall solutions are non-singular. We point out that the presence of the Gauss-Bonnet term does not allow flat solutions with localized gravity that violate the wea...
متن کاملCompletely localized gravity with higher curvature terms
In the intersecting braneworld models, higher curvature corrections to the Einstein action are necessary to provide a non-trivial geometry (brane tension) at the brane junctions. By introducing such terms in a Gauss-Bonnet form, we give an effective description of localized gravity on the singular delta-function branes. There exists a non-vanishing brane tension at the four-dimensional brane in...
متن کاملQuantum Gravity and Higher Curvature Actions
Effective equations are often useful to extract physical information from quantum theories without having to face all technical and conceptual difficulties. One can then describe aspects of the quantum system by equations of classical type, which correct the classical equations by modified coefficients and higher derivative terms. In gravity, for instance, one expects terms with higher powers o...
متن کاملCollider Signatures of Higher Curvature Gravity
is the basis for General Relativity(GR) in 4d as well as the ADD[1] and RS[2] models in extra dimensions. As is well known EH is at best an effective action below the scale M∗. As energies approaching M∗ are reached additional terms may be generated in the effective action arising from the UV-completion of GR, e.g., string theory. If M∗ is not far above the TeV scale then these additional terms...
