在M和II型弦理论中，我们研究了带有低维薄膜电荷、包裹黑洞和黑洞微态的扩展薄膜的动力学。我们证明了它们具有普遍的色散关系，其总能量等于电荷贡献之和的阈值束缚态。在黑洞的近视界几何中，这些是BPS态，色散关系源于超对称性和共形代数的性质。然而，它们破坏了黑洞和微态的全部渐近几何的所有超对称性。我们评论了最近一项使用这些态来解释黑洞熵的提议。
We examine the dynamics of extended branes, carrying lower-dimensional brane charges, wrapping black holes and black hole microstates in M and type II string theory. We show that they have a universal dispersion relation typical of threshold bound states with a total energy equal to the sum of the contributions from the charges. In near-horizon geometries of black holes, these are BPS states, and the dispersion relation follows from supersymmetry as well as properties of the conformal algebra. However they break all supersymmetries of the full asymptotic geometries of black holes and microstates. We comment on a recent proposal which uses these states to explain black hole entropy.
