Dynamic properties of self-interacting Fuzzy Dark Matter soliton cores

We investigate the effect of self-interactions on the shape and oscillations of the solitonic core profile of condensed fuzzy dark matter systems without the backdrop of a halo, revealing universal features in terms of an appropriately scaled interaction strength characterizing the crossover between the weakly- and strongly-interacting regimes. Our semi-analytical results are further confirmed by spherically symmetric simulations of the Gross-Pitaevskii-Poisson equations. Inverting our obtained relations, we highlight a degeneracy that could significantly affect constraints on the boson mass in the presence of repulsive boson self-interactions and propose the simultaneous extraction of static and dynamical solitonic features as a way to uniquely constrain both the boson mass and self-interactions.The figure data in this dataset underpin the peer-reviewed paper 'Virialized Profiles and Oscillations of Self-interacting Fuzzy Dark Matter Solitons'.

本研究探讨在无晕背景下，凝聚态模糊暗物质系统的孤子核心轮廓的形状和振荡受自相互作用影响的现象，揭示了在适当缩放的作用强度下，弱相互作用与强相互作用之间过渡的普适特征。我们的半解析结果通过球对称的Gross-Pitaevskii-Poisson方程的模拟进一步得到验证。通过对我们获得的关系进行逆运算，我们突出了可能显著影响排斥性玻色子自相互作用存在下玻色子质量约束的简并性，并提出同时提取静态和动态孤子特征作为唯一约束玻色子质量和自相互作用的方法。本数据集中的图数据为本领域同行评审论文《自相互作用模糊暗物质孤子的virialized轮廓和振荡》提供了支撑。可在arXiv上查阅预印本。
