Breakdown of the Mechanism of Forming Wakes by a Current-Carrying String
نویسندگان
چکیده
In this letter we emphasize the effect that the inclusion of electromagnetic properties for a string brings logarithmic divergences to the accretion problem and the mechanism of formation and evolution of wakes can break down.

In this work, we present the gravitational field generated by a cosmic string carrying a timelike current in the scalar-tensor gravities. The mechanism of formation and evolution of wakes is fully investigated in this framework. We show explicitly that the inclusion of electromagnetic properties for the string induces logarithmic divergences in the accretion problem.

متن کاملFormation of Wakes by Chiral Conducting Cosmic Strings
Topological defects are predicted in many gauge models as solitonic solutions resulting from spontaneous breaking of gauge or global symmetries. Among all these solutions, cosmic strings, and in particular those with conducting properties, have a number of cosmological applications.1 The possible scenarios for structure formation by cosmic strings depend very much in the detail of the model. On...
متن کاملImpact of Pollution Location on Time and Frequency Characteristics of Leakage Current of Porcelain Insulator String under Different Humidity and Contamination Severity
One of the important factors influencing outdoor insulators performance is pollution phenomenon. The pollution, especially during humidity condition, reduces superficial resistance of insulator and lead to a flow of Leakage Currents (LC) on the insulator surface, which may result in total flashover. The LC characteristics are affected by parameters such as nature and severity of pollution. Loca...
