Supertubes in Bubbling Backgrounds: Born-Infeld Meets Supergravity
Iosif Bena, Nikolay Bobev, Clement Ruef +1
We discuss two ways in which one can study two-charge supertubes as components of generic three-charge, three-dipole charge supergravity solutions. The first is using the Born-Infe…
Entropy Enhancement and Black Hole Microstates
Iosif Bena, Nikolay Bobev, Clement Ruef +1
We study fluctuating two-charge supertubes in three-charge geometries. We show that the entropy of these supertubes is determined by their locally-defined effective charges, which…
Spectral Flow, and the Spectrum of Multi-Center Solutions
Iosif Bena, Nikolay Bobev, Nicholas P. Warner
We discuss "spectral flow" coordinate transformations that take asymptotically four-dimensional solutions into other asymptotically four-dimensional solutions. We find that spectra…
