Non-extreme Calabi-Yau black holes

چکیده

Non-extreme black hole solutions of four dimensional, N = 2 supergravity theories with Calabi-Yau prepotentials are presented, which generalize certain known doubleextreme and extreme solutions. The boost parameters characterizing the nonextreme solutions must satisfy certain constraints, which effectively limit the functional independence of the moduli scalars. A necessary condition for being able to take certain boost parameters independent is found to be block diagonality of the gauge coupling matrix. We present a number of examples aimed at developing an understanding of this situation and speculate about the existence of more general solutions.

Calabi-yau Black Holes

We have found the entropy of N=2 extreme black holes associated with general Calabi-Yau moduli space and prepotential F = dABC XXX X0 . We show that for arbitrary dABC and black hole charges p and q the entropy-area formula depends on combinations of these charges and parameters dABC . These combinations are the solutions of the simple system of algebraic equations. We gave a few examples of pa...

Calabi-Yau Compactification of Type-IIB String and a Mass Formula of the Extreme Black Holes

Recently proposed mechanism of the black hole condensation at conifold singularity in type II string is an interesting idea from which we can interpret the phase of the universal moduli space of the string vacua. It might also be expected that the true physics is on the conifold singularity after supersymmetry breaking. We derive a mass formula for the extreme black holes caused by the self-dua...

String Vacua with N = 2 Supersymmetry in Four Dimensions

In this article we review four-dimensional string vacua with N = 2 space-time supersymmetry. In particular, we will discuss several aspects of the string-string duality between the heterotic string, compactified on K3 × T 2 , and the type II superstring compactified on a Calabi-Yau threefold. We investigate the massless supersymmetric spectra, showing agreement for a large class of dual heterot...

Black Holes and Calabi-Yau Threefolds

We compute the microscopic entropy of certain 4 and 5 dimensional extermal black holes which arise for compactification of M-theory and type IIA on Calabi-Yau 3-folds. The results agree with macroscopic predictions, including some subleading terms. The macroscopic entropy in the 5 dimensional case predicts a surprising growth in the cohomology of moduli space of holomorphic curves in Calabi-Yau...
