Phys. Rev. Lett. 88, 211303 (2002) [4 pages]Statistical Interpretation of the Bekenstein Entropy for Systems with a Stretched HorizonReceived 12 February 2002; published 14 May 2002 For the two-charge extremal holes in string theory we show that the Bekenstein entropy obtained from the area of the stretched horizon has a statistical interpretation as a “coarse graining entropy”: different microstates give geometries that differ near r = 0, and the stretched horizon cuts off the metric at r = b where these geometries start to differ. © 2002 The American Physical Society URL:
