Non-Supersymmetric Attractors in Symmetric Coset Spaces
The attractor mechanism for supersymmetric (BPS) black holes was discovered in 1995 [1]: at the horizon of a supersymmetric black hole, the moduli are completely determined by the charges of the black hole, independent of their asymptotic values. In 2005, Sen showed that all extremal black holes, both supersymmetric and non-supersymmetric (non-BPS), exhibit attractor behavior [2]: it is a resul...
متن کاملNon-Supersymmetric Attractors in R Gravities
We investigate the attractor mechanism for spherically symmetric extremal black holes in a theory of general R2 gravity in 4-dimensions, coupled to gauge fields and moduli fields. For the general R2 theory, we look for solutions which are analytic near the horizon, show that they exist and enjoy the attractor behavior. The attractor point is determined by extremization of an effective potential...
متن کاملNon-Supersymmetric Attractors in BI black holes
We study attractor mechanism in extremal black holes of Einstein-BornInfeld theories in four dimensions. We look for solutions which are regular near the horizon and show that they exist and enjoy the attractor behavior. The attractor point is determined by extremization of the effective potential at the horizon. This analysis includes the backreaction and supports the validity of non-supersymm...
متن کاملSupersymmetric Multiple Basin Attractors
We explain that supersymmetric attractors in general have several critical points due to the algebraic nature of the stabilization equations. We show that the critical values of the cosmological constant of the adS5 vacua are given by the topological (moduli-independent) formulae analogous to the entropy of the d = 5 supersymmetric black holes. In one-moduli case critical points with positive d...
متن کاملUniversality of supersymmetric attractors.
The macroscopic entropy-area formula for supersymmetric black holes in N=2,4,8 theories is found to be universal: in d=4 it is always given by the square of the largest of the central charges extremized in the moduli space. The proof of universality is based on the fact that the doubling of unbroken supersymmetry near the black hole horizon requires that all central charges other than Z=M vanis...
