Brane-Waves and Strings
Recently, solutions of the Born-Infeld theory representing strings emanating from a Dirichlet p-brane have been constructed. We discuss the embedding of these Born-Infeld solutions into the non-abelian theory appropriate to multiple overlapping p-branes. We also prove supersymmetry of the solutions explicitly in the full nonlinear theory. We then study transverse fluctuations, both from the wor...
متن کاملBrane Partons and Singleton Strings
We examine p-branes in AdSD in two limits where they exhibit partonic behavior: rotating branes with energy concentrated to cusp-like solitons; tensionless branes with energy distributed over singletonic bits on the Dirac hypercone. Evidence for a smooth transition from cusps to bits are found. First, each cusp yields D−2 normal-coordinate bound states with protected frequencies; and is dual to...
متن کاملSelf Gravitating Fundamental Strings
We study the configuration of a typical highly excited string as one slowly increases the string coupling. The dominant interactions are the long range dilaton and gravitational attraction. In four spacetime dimensions, the string slowly contracts from its initial (large) size until it approaches the string scale where it forms a black hole. In higher dimensions, the string stays large until th...
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 کاملClassical splitting of fundamental strings.
We find exact solutions of the string equations of motion and constraints describing the classical splitting of a string into two. We show that for the same Cauchy data, the strings that split have smaller action than the string without splitting. This phenomenon is already present in flat space-time. The mass, energy and momentum carried out by the strings are computed. We show that the splitt...
