  A brane-antibrane model for the entropy of neutral black branes is developed,
following on from the work of Danielsson, Guijosa and Kruczenski [1]. The model
involves equal numbers of Dp-branes and anti-Dp-branes, and arbitrary angular
momenta, and covers the cases p=0,1,2,3,4. The thermodynamic entropy is
reproduced by the strongly coupled field theory, up to a power of two. The
strong-coupling physics of the p=0 case is further developed numerically, using
techniques of Kabat, Lifschytz et al. [2,3], in the context of a toy model
containing the tachyon and the bosonic degrees of freedom of the D0-brane and
anti-D0-brane quantum mechanics. Preliminary numerical results show that
strong-coupling finite-temperature stabilization of the tachyon is possible, in
this context.
