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 کاملBlack Holes as Fundamental Strings: Comparing the Absorption of Scalars
The recently proposed “correspondence principle” of Horowitz and Polchinski provides a concrete means to relate (among others) black holes with electric NS-NS charges to fundamental strings and correctly match their entropies. We test further this correspondence by examining the greybody factors in the absorption rates of neutral, minimally coupled scalars by a near extremal black hole. Perhaps...
متن کاملBlack holes from nucleating strings.
We evaluate the probability that a loop of string that has spontaneously nucleated during inflation will form a black hole upon collapse, after the end of inflation. We then use the observational bounds on the density of primordial black holes to put constraints on the parameters of the model. Other constraints from the distortions of the microwave background and emission of gravitational radia...
متن کاملQuantum Strings and Black Holes
The transition between (non supersymmetric) quantum string states and Schwarzschild black holes is discussed. This transition occurs when the string coupling g2 (which determines Newton’s constant) increases beyond a certain critical value g2 c . We review a calculation showing that self-gravity causes a typical string state of mass M to shrink, as the string coupling g2 increases, down to a co...
