黑洞熵、弯曲空间和怪物

Black hole entropy, curved space and monsters

Stephen D. H. Hsu, David Reeb

摘要:

我们研究了黑洞熵的微观起源,特别是普通物质与黑洞的最大熵之间的差距。利用弯曲空间,我们构造熵大于普朗克单位面积的组态。这些结构具有病态的性质,我们称之为怪物。当排除怪物时,我们恢复了普通物质$S < A^{3/4}$的熵束缚。这个界限意味着,基本上半经典黑洞的所有微观态都与一个稍微小一点的黑洞的生长有关,这个黑洞吸收了一些额外的能量。我们的结果表明,黑洞的面积熵是由普通物质和较小的黑洞形成黑洞的不同方式的对数,但只有在排除怪物状态之后。

英文摘要:

We investigate the microscopic origin of black hole entropy, in particular the gap between the maximum entropy of ordinary matter and that of black holes. Using curved space, we construct configurations with entropy greater than their area in Planck units. These configurations have pathological properties and we refer to them as monsters. When monsters are excluded we recover the entropy bound on ordinary matter $S < A^{3/4}$. This bound implies that essentially all of the microstates of a semiclassical black hole are associated with the growth of a slightly smaller black hole which absorbs some additional energy. Our results suggest that the area entropy of black holes is the logarithm of the number of distinct ways in which one can form the black hole from ordinary matter and smaller black holes, but only after the exclusion of monster states.
