Fundamental Plasmid Strings and Black Rings
Jose J. Blanco-Pillado, Roberto Emparan, Alberto Iglesias
We construct excited states of fundamental strings that admit a semiclassical description as rotating circular loops of string. We identify them with the supergravity solutions for…
Evolution of cosmic superstring networks: a numerical simulation
Jon Urrestilla, Alexander Vilenkin
We study the formation and evolution of an interconnected string network in large-scale field-theory numerical simulations, both in flat spacetime and in expanding universe. The ne…
Prediction and explanation in the multiverse
Jaume Garriga, Alexander Vilenkin
Probabilities in the multiverse can be calculated by assuming that we are typical representatives in a given reference class. But is this class well defined? What should be include…
Cosmic string formation by flux trapping
Jose J. Blanco-Pillado, Ken D. Olum, Alexander Vilenkin
We study the formation of cosmic strings by confining a stochastic magnetic field into flux tubes in a numerical simulation. We use overdamped evolution in a potential that is mini…
On Semiclassical Limits of String States
Jose J. Blanco-Pillado, Alberto Iglesias, Warren Siegel
We explore the relation between classical and quantum states in both open and closed (super)strings discussing the relevance of coherent states as a semiclassical approximation. Fo…
Eternal inflation, bubble collisions, and the persistence of memory
Jaume Garriga, Alan H. Guth, Alexander Vilenkin
A ``bubble universe'' nucleating in an eternally inflating false vacuum will experience, in the course of its expansion, collisions with an infinite number of other bubbles. In an…
