Abstract
A point-particle treatment for the statistical mechanics of Bogomol’nyi-Prasad-Sommerfield (BPS) black holes in Einstein-Maxwell-dilaton theory is developed. Because of the absence of the static potential, the canonical partition function for N BPS black holes can be expressed by the volume of the moduli space for them. We estimate the equation of state for a classical gas of BPS black holes by the Padé approximation and find that the result agrees with the one obtained by the mean-field approximation.
