TL;DR

This paper constructs a microstate model for a black ring involving a black string microstate and a D6-brane, revealing a long AdS throat and a dielectric D2-brane configuration, advancing understanding of black ring microstates.

Contribution

It introduces a novel microstate configuration for black rings combining black string microstates with D6-branes and explores the dielectric D2-brane behavior in this context.

Findings

Microstate involves black string and D6-brane components.

Long AdS throat appears in the microstate geometry.

D2-brane exhibits Myers effect, indicating D0-brane polarization.

Abstract

We present a sample microstate for a black ring in four and five dimensional language. The microstate consists of a black string microstate with an additional D6-brane. We show that with an appropriate choice of parameters the piece involving the black string microstate falls down a long AdS throat, whose M-theory lift is AdS_3 X S^2. We wrap a spinning dipole M2-brane on the S^2 in the probe approximation. In IIA, this corresponds to a dielectric D2-brane carrying only D0-charge. We conjecture this is the first approximation to a cloud of D0-branes blowing up due to their non-abelian degrees of freedom and the Myers effect.
