Comments on Supergravity Description of S-branes
Alex Buchel, Johannes Walcher
This is a note on the coupled supergravity-tachyon matter system, which has been earlier proposed as a candidate for the effective space-time description of S-branes. In particular…
The quest for a conifold conformal order
Alex Buchel
The holographic duality between cascading gauge theory and type IIB supergravity on warped deformed conifold with fluxes reveals exotic thermal phases with nonzero expectation valu…
Instability of 5D Gauss-Bonnet black branes
Alex Buchel, Raphael E. Hoult, Pavel Kovtun
We show that Gauss-Bonnet black branes in five-dimensional anti-de Sitter gravity are unstable when the Gauss-Bonnet coupling falls outside the range allowed by the conformal colli…
Throat destabilization (for profit and for fun)
Iosif Bena, Alex Buchel, Severin Lüst
Two recent results indicate that the addition of supersymmetry-breaking ingredients can destabilize the Klebanov-Strassler warped deformed conifold throat. The first comes from an…
Horizons cannot save the Landscape
Iosif Bena, Alex Buchel, Oscar J. C. Dias
Solutions with anti-D3 branes in a Klebanov-Strassler geometry with positive charge dissolved in fluxes have a certain singularity corresponding to a diverging energy density of th…
Reply to "Comment on two-mode stability islands around AdS"
Alex Buchel, Stephen R. Green, Luis Lehner +1
We respond to the criticisms of a recent comment by BizoÅ and Rostworowski [arXiv:1410.2631].
