Volterra Distortions, Spinning Strings, and Cosmic Defects
Cosmic strings, as topological spacetime defects, show striking resemblance to defects in solid continua: distortions, which can be classified into disclinations and dislocations, are linelike defects characterized by a delta function-valued curvature and torsion distribution giving rise to rotational and translational holonomy. We exploit this analogy and investigate how distortions can be ada...
متن کاملComment on "Spinning cosmic strings and quantization of energy"
The preceding comment [1] has raised the question of the validity of the argument presented in the Letter [2] that the energy of the particles should be quantized in the background of a spinning cosmic string. As the construction of the electromagnetic analogy given in [2] suggests, a spinning cosmic string is the gravitational analog of the Aharonov-Bohm solenoid (flux tube), and the angular m...
متن کاملSpinning cosmic strings: a general class of solutions
In this work, we give a general class of solutions of the spinning cosmic string in Einstein’s theory of gravity. After treating same problem in Einstein Cartan (EC) theory of gravity, the exact solution satisfying both exterior and interior space-times representing a spin fluid moving along the symmetry axis is presented in the EC theory. The existence of closed timelike curves in this spaceti...
متن کاملCosmic Strings and Cosmic Supertrings
In these lectures, I review the current status of cosmic strings and cosmic superstrings. I first discuss topological defects in the context of Grand Unified Theories, focusing in particular in cosmic strings arising as gauge theory solitons. I discuss the reconciliation between cosmic strings and cosmological inflation, I review cosmic strings dynamics, cosmic string thermodynamics and cosmic ...
متن کاملSpinning Dragging Strings
We use the AdS/CFT correspondence to compute the drag force experienced by a heavy quark moving through a N = 4 SU(N) super Yang-Mills plasma at nonzero temperature and R-charge chemical potential and at large ’t Hooft coupling. We resolve a discrepancy in the literature between two earlier studies of such quarks. In addition, we consider small fluctuations of the spinning strings dual to these...
