Compactification Effects in D-brane Inflation
Daniel Baumann, Anatoly Dymarsky, Shamit Kachru +2
We determine the scalar potential for a D3-brane in a warped conifold background subject to general ultraviolet perturbations. Incorporating the effects of imaginary anti-self-dual…
Emergent Quantum Near-Criticality from Baryonic Black Branes
Christopher P. Herzog, Igor R. Klebanov, Silviu S. Pufu +1
We find new black 3-brane solutions describing the "conifold gauge theory" at nonzero temperature and baryonic chemical potential. Of particular interest is the low-temperature lim…
M2-branes and AdS/CFT
Igor R. Klebanov, Giuseppe Torri
These notes provide a brief introduction to the ABJM theory, the level k U(N) x U(N) superconformal Chern-Simons matter theory which has been conjectured to describe N coincident M…
Charges of Monopole Operators in Chern-Simons Yang-Mills Theory
Marcus K. Benna, Igor R. Klebanov, Thomas Klose
We calculate the non-abelian R-charges of BPS monopole operators in three-dimensional gauge theories with N=3 supersymmetry. This class of models includes ABJM theory, the proposed…
The Squashed, Stretched, and Warped Gets Perturbed
Igor R. Klebanov, Silviu S. Pufu, Fabio D. Rocha
We use direct Kaluza-Klein reduction to calculate the spectrum of spin-2 modes around a warped product of AdS_4 and a certain squashed and stretched 7-sphere. The modes turn out to…
M2-branes on Orbifolds of the Cone over Q^{1,1,1}
Sebastian Franco, Igor R. Klebanov, Diego Rodriguez-Gomez
We study the N=2 supersymmetric Chern-Simons quiver gauge theory recently introduced in arXiv:0809.3237 to describe M2-branes on a cone over the well-known Sasaki-Einstein manifold…
