Stability analysis for -balls with spectral method
Qian Chen, Lars Andersson, Li Li
Based on the spectral decomposition technique, we introduce a simple and universal numerical method to analyze the stability of solitons. Adopting this method, the linear dynamical…

Hydrodynamic and Rayleigh-Plateau instabilities of Q-strings
Qian Chen
As analogues of compact objects, solitons have attracted significant attention. We reveal that cylindrical Q-strings exhibit a dynamical instability to perturbations with wavelengt…
