$\Delta-$string - a hybrid between wormhole and string

TL;DR

This paper introduces the concept of a $ abla$-string, a string-like object in 5D Kaluza-Klein theory, highlighting its unique properties such as the absence of critical dimensions, and explores electromagnetic wave propagation through it.

Contribution

It presents the $ abla$-string as a novel hybrid between wormholes and strings, derived from flux tube solutions in 5D Kaluza-Klein theory, and analyzes its distinctive features.

Findings

$ abla$-string lacks critical dimensions unlike ordinary strings

Electromagnetic waves can propagate through the $ abla$-string

The $ abla$-string is a hybrid between wormholes and strings

Abstract

The flux tube solutions in 5D Kaluza-Klein theory can be considered as a string-like object - $\Delta-$string. The initial 5D metric can be reduced to some inner degrees of freedom living on the $\Delta-$string. The propagation of electromagnetic waves through the $\Delta-$string is considered. It is shown that the difference between $\Delta$ and ordinary strings are connected with the fact that for the $\Delta-$string such limitations as critical dimensions are missing.
