标题： Metastable Supertubes and non-extremal Black Hole Microstates

摘要： 我们研究了在具有三个电荷和三个偶极电荷的平滑泡状几何中，超管的动力学，这些几何可以描述黑洞、黑环及其微观状态。 我们在这些背景中找到了超管哈密顿量，并表明存在亚稳态超管配置，可以通过膜-通量湮灭衰变为超对称和非超对称配置。 我们还发现了稳定的非超对称配置。 亚稳态和稳定非超对称配置都被预期描述非极端黑洞的微观状态几何，并我们讨论了它们的存在对模糊球提议的意义。 显示英文摘要

摘要： We study the dynamics of supertubes in smooth bubbling geometries with three charges and three dipole charges that can describe black holes, black rings and their microstates. We find the supertube Hamiltonian in these backgrounds and show that there exist metastable supertube configurations, that can decay into supersymmetric and non-supersymmetric ones via brane-flux annihilation. We also find stable non-supersymmetric configurations. Both the metastable and the stable non-supersymmetric configuration are expected to describe microstate geometries for non-extremal black holes, and we discuss the implication of their existence for the fuzzball proposal.
