摘要
En 中文
In this paper we study spherically symmetric single-centered attractors in N = 2 supergravity in four dimensions. The attractor points are obtained by extremising the effective black hole potential in the moduli space. Both supersymmetric as well as non-supersymmetric attractors exist in mutually exclusive domains of the charge lattice. We construct axion free supersymmetric as well as non-supersymmetric multiple attractors in a simple two parameter model. We further obtain explicit examples of two distinct non-supersymmetric attractors in type I I A string theory compactified on K3 x T-2 carrying D0 - D4 - D6 charges. We compute the entropy of these attractors and analyse their stability in detail.
