圈引力提供了黑洞熵的微观推导。在本文中，我表明，微观状态计数承认半经典描述的形状的棋盘格地平线。微观状态的计数和熵的计算可以通过映射到一个等价的统计力学问题来完成：闭合聚合物链构象的计数。这种对应关系暗示了黑洞热力学和聚合物物理学之间的许多有趣关系。
Loop gravity provides a microscopic derivation of black hole entropy. In this paper, I show that the microstates counted admit a semiclassical description in terms of shapes of a tessellated horizon. The counting of microstates and the computation of the entropy can be done via a mapping to an equivalent statistical mechanical problem: the counting of conformations of a closed polymer chain. This correspondence suggests a number of intriguing relations between the thermodynamics of black holes and the physics of polymers.
