Black - Hole Attractors in N = 1 Supergravity
We study the attractor mechanism for N = 1 supergravity coupled to vector and chiral multiplets and compute the attractor equations of these theories. These equations may have solutions depending on the choice of the holomorphic symmetric matrix f ΛΣ which appears in the kinetic lagrangian of the vector sector. Models with non trivial electric-magnetic duality group which have or have not attra...
متن کاملBlack Hole Attractors in Extended Supergravity
We review some aspects of the attractor mechanism for extremal black holes of (not necessarily supersymmetric) theories coupling Einstein gravity to scalars and Maxwell vector fields. Thence, we consider N = 2 and N = 8, d = 4 supergravities, reporting some recent advances on the moduli spaces associated to BPS and nonBPS attractor solutions supported by charge orbits with non-compact stabilize...
متن کاملBlack hole entropy and attractors
The introductory lectures delivered at the 2006 RTN Winter School on Strings, Supergravity and Gauge Theories at CERN and the 2005 Shanghai Summer School on Recent Trends in M/String Theory were aimed at Ph.D students and recent postdocs. We describe recent progress in understanding quantum aspects of black holes after reviewing the relevant background material, and illustrate the basic concept...
متن کاملd 4 black hole attractors in N 2 supergravity with Fayet - Iliopoulos terms
We generalize the description of the d = 4 Attractor Mechanism based on an effective black hole (BH) potential to the presence of a gauging which does not modify the derivatives of the scalars and does not involve hypermultiplets. The obtained results do not rely necessarily on supersymmetry, and they can be extended to d > 4, as well. Thence, we work out the example of the stu model of N = 2 s...
متن کاملComplex Multiplication Symmetry of Black Hole Attractors
We show how Moore’s observation, in the context of toroidal compactifications in type IIB string theory, concerning the complex multiplication structure of black hole attractor varieties, can be generalized to Calabi-Yau compactifications with finite fundamental groups. This generalization leads to an alternative general framework in terms of motives associated to a Calabi-Yau variety in which ...
