婴儿Skyrmions在AdS

Baby Skyrmions in AdS

Matthew Elliot-Ripley, Thomas Winyard

摘要:

我们研究了无质量项的纯AdS背景下的婴儿Skyrme模型。无质量径向解的尾部衰变和标度被证明采取类似的形式,与大规模的平坦空间模型,与AdS曲率起着类似的作用,平坦的空间π介子质量。我们还数值上找到最小能量的解决方案,为一系列较高的拓扑电荷,并发现它们形成同心环状的解决方案。爆米花过渡(命名与全息QCD的玩具模型的研究)从n层到n+1层的配置观察到拓扑电荷9和27和更高的费用进一步爆米花过渡的预测。最后,一个点粒子近似的模型推导出并成功地预测了高电荷孤子的环形结构和爆米花跃迁。

英文摘要:

We study the baby Skyrme model in a pure AdS background without a mass term. The tail decays and scalings of massless radial solutions are demonstrated to take a similar form to those of the massive flat space model, with the AdS curvature playing a similar role to the flat space pion mass. We also numerically find minimal energy solutions for a range of higher topological charges and find that they form concentric ring-like solutions. Popcorn transitions (named in analogy with studies of toy models of holographic QCD) from an n layer to an n+1-layer configuration are observed at topological charges 9 and 27 and further popcorn transitions for higher charges are predicted. Finally, a point-particle approximation for the model is derived and used to successfully predict the ring structures and popcorn transitions for higher charge solitons.
