Vacuum Tunneling by Cosmic Strings
We consider vacuum tunneling of a new kind where the false vacua are not translationally invariant, but have topological defects that break some of their translational symmetries. In the particular case where the topological defects are cosmic strings, we show the existence of an O(2)×O(2) symmetric bounce configuration that allows a semi-classical estimate of the rate of cosmic string induced ...
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 کاملCosmic Strings & Cosmic Variance
By using a simple analytical model based on counting random multiple impulses inflicted on photons by a network of cosmic strings we show how to construct the general q-point temperature correlation function of the Cosmic Microwave Background radiation. Our analysis is sensible specially for large angular scales where the Kaiser-Stebbins effect is dominant. Then we concentrate our study on the ...
متن کاملec 2 01 5 Long polymers near wedges and cones
We perform a Monte Carlo study of N-step self-avoiding walks, attached to the corner of an impenetrable wedge in two dimensions (d = 2), or the tip of an impenetrable cone in d = 3, of sizes ranging up to N = 10 steps. We find that the critical exponent γα, which determines the dependence of the number of available conformations on N for a cone/wedge with opening angle α, is in good agreement w...
متن کاملElectrostatic "Fractional" Image Methods for Perfectly Conducting Wedges and Cones
In our earlier work, we introduced a definition for the electric charge "fractional-order" multipoles using the concept of fractional derivatives and integrals [l]. Here, we utilize that definition to introduce a detailed image theory for the two-dimensional (2-D) electrostatic potential distributions in front of a perfectly conducting wedge with arbitrary wedge angles, and for the three-dimens...
