Generalized BIons in M-theory
Chethan Krishnan
In string theory, stacks of D1-branes can expand into intersecting D3-branes. These configurations are called (generalized) BIons. We show how the analogous constructions in M-theo…
Tomograms of Spinning Black Holes
Chethan Krishnan
The classical internal structure of spinning black holes is vastly different from that of static black holes. We consider spinning BTZ black holes, and probe their interior from th…
A Comment on Kerr-CFT and Wald Entropy
Chethan Krishnan, Stanislav Kuperstein
We point out that the entropies of black holes in general diffeomorphism invariant theories, computed using the Kerr-CFT correspondence and the Wald formula (as implemented in the…
M2-brane Flows and the Chern-Simons Level
Chethan Krishnan, Carlo Maccaferri, Harvendra Singh
The Chern-Simons level k of ABJM gauge theory captures the orbifolding in the dual geometry. This suggests that if we move the membranes away from the tip of the orbifold to a smoo…
