Improved Stability for Pulsating Multi-Spin String Solitons

TL;DR

This paper demonstrates that pulsations in S(5) enhance the stability of two-spin string solitons in AdS(5), allowing for higher spins while maintaining stability through analytical and numerical analysis.

Contribution

It introduces a novel analysis showing how pulsations improve the stability range of multi-spin string solitons in AdS(5) x S(5).

Findings

Pulsation increases the maximum allowed spin for stability.

Analytical and numerical methods confirm stability improvements.

Higher pulsation correlates with enhanced stability properties.

Abstract

We derive and analyse, analytically and numerically, the equations for perturbations around the pulsating two-spin string soliton in AdS(5) x S(5).We show that the pulsation in S(5) indeed improves the stability properties of the two-spin string soliton in AdS(5), in the sense that the more pulsation we have, the higher spin we can allow and still have stability.
