String Gas Shells, their Dual Radiation and Hedgehog Signature Control

TL;DR

This paper explores spherically symmetric solutions with string gas shells, revealing a dual radiation linked to quantum fluctuations and analyzing how hedgehog defects influence the shell's properties and stability.

Contribution

It introduces a new class of solutions involving string gas shells with dual radiation and hedgehog defects, connecting classical configurations to quantum fluctuation interpretations.

Findings

Dual radiation can be spacelike or timelike depending on hedgehog strength.

String gas shells are regular for small hedgehog strengths.

Solutions suggest a link between classical string configurations and quantum fluctuations.

Abstract

We search for spherically symmetric, stationary solutions with a string gas shell as a source. The requirement of a uniform newtonian potential, or constancy of the 00 component of the metric, implies the existence of a "dual" radiation, which we argue can be interpreted as representing the virtual quantum fluctuations that stabilize the shell. A string hedgehog can be introduced also into the solution. For zero or small hedgehog strength the string gas shell is of a regular nature, while the dual radiation is of a spacelike nature. For higher hedgehog strengths however the radiation "materializes" and becomes timelike while the string gas shell becomes space like. The significance of these solutions for the quantum theory is discussed.
