Cinderella Strings
A. Achucarro, R. Gregory, J. A. Harvey +1
We investigate recent claims concerning a new class of cosmic string solutions in the Weinberg-Salam model. They have the general form of previously discussed semi-local and electr…
Do Global String Loops Collapse to Form Black Holes?
Joaquim Fort, Tanmay Vachaspati
Hawking has shown that the emission of gravitational radiation cannot prevent circular loops of gauged cosmic strings from collapsing into black holes. Here we consider the corresp…
Relating black holes in two and three dimensions
Ana Achúcarro, Miguel Ortiz
The three dimensional black hole solutions of Bañados, Teitelboim and Zanelli (BTZ) are dimensionally reduced in various different ways. Solutions are obtained to the Jackiw-Teitel…
Effects of friction on cosmic strings
J. Garriga, M. Sakellariadou
We study the evolution of cosmic strings taking into account the frictional force due to the surrounding radiation. We consider small perturbations on straight strings, oscillation…
