Strings as Solitons & Black Holes as Strings
Supersymmetric closed string theories contain an infinite tower of BPS-saturated, oscillating, macroscopic strings in the perturbative spectrum. When these theories have dual formulations, this tower of states must exist nonperturbatively as solitons in the dual theories. We present a general class of exact solutions of low-energy supergravity that corresponds to all these states. After dimensi...
متن کاملStrings and black holes
I review some recent work (done in collaboration with G. Veneziano) which clarifies the existence of a correspondence between self-gravitating fundamental string states and Schwarzschild black holes. The main result is a detailed calculation showing that selfgravity causes a typical string state of mass M to shrink, as the string coupling g increases, down to a compact string state whose mass, ...
متن کاملOn Black Fundamental Strings
We study aspects of four dimensional black holes with two electric charges, corresponding to fundamental strings with generic momentum and winding on an internal circle. The perturbative α correction to such black holes and their gravitational thermodynamics is obtained.
متن کاملPlaying with Black Strings
We review recent work showing that there exists a large class of new stable black strings which are not translationally invariant. Both neutral and charged black strings are considered. The discussion includes known properties of these new solutions, attempts to find them explicitly, and a list of open questions. 1 To appear in the proceedings of Stephen Hawking’s 60 birthday conference, Cambri...
متن کاملOn Generating Independent Random Strings
It is shown that from two strings that are partially random and independent (in the sense of Kolmogorov complexity) it is possible to effectively construct polynomially many strings that are random and pairwise independent. If the two initial strings are random, then the above task can be performed in polynomial time. It is also possible to construct in polynomial time a random string, from two...
