Exact results for the BPS index are known for a class of BPS dyons in type II string theory compactified on a six dimensional torus. In this paper we set up the problem of counting the same BPS states in a duality frame in which the states carry only Ramond-Ramond charges. We explicitly count the number of states carrying the lowest possible charges and find agreement with the result obtained in other duality frames. Furthermore, we find that after factoring out the supermultiplet structure, each of these states carry zero angular momentum. This is in agreement with the prediction obtained from a representation of these states as supersymmetric black holes.

  1. Classical Unattainability of Extremality in non-BPS D-brane Systems

    hep-th 2026-01 conditional novelty 6.0

    For a non-BPS four-charge D-brane system in N=8 string theory, the worldline potential has no classical zero-energy minimum, so extremality is unattainable; entropy is proposed as the logarithm of the number of isolat...

  2. An extremal black hole with a unique ground state

    hep-th 2024-11 unverdicted novelty 6.0

    Microscopic D-brane description of non-supersymmetric extremal black holes yields a unique ground state with non-zero energy, confirming absence of degeneracy.

  3. Pure D-brane Black Holes: BPS Counting and non-BPS Vacua

    hep-th 2026-01 conditional novelty 5.0

    The (1,1,1,5) and (1,1,1,6) D2-D2-D2-D6 BPS systems yield 2032 and 5616 vacua, matching U-duality, while the analogous non-BPS system has no zero-energy vacua and six doubly-degenerate low-energy minima.
