Classical Unattainability of Extremality in non-BPS D-brane Systems
Pranav Kumar, Swapnamay Mondal
For the worldline theory of an extremal black hole, extremality amounts to vanishing ground state energy. In light of recent gravity results one would expect much like the ground s…
An extremal black hole with a unique ground state
Swapnamay Mondal
Recent computations in gravity suggest that non-supersymmetric extremal black holes lack any sizeable ground state degeneracy. We confirm this for D-brane description of non-supers…
Non-trivial saddles in microscopic description of black holes
Pranav Kumar, Swapnamay Mondal
Non-trivial gravitational saddles have played a key role in the island proposal for the black hole information paradox. It is worth asking if non-trivial saddles exist in microscop…
Statistical Mechanics of Exponentially Many Low Lying States
Swapnamay Mondal
It has recently been argued that for near-extremal black holes, the entropy and the energy above extremality respectively receive a logT and a T-linear correction, where T is the t…
Black holes and the loss landscape in machine learning
Pranav Kumar, Taniya Mandal, Swapnamay Mondal
Understanding the loss landscape is an important problem in machine learning. One key feature of the loss function, common to many neural network architectures, is the presence of…
Supersymmetric black holes and deformation
Jan Manschot, Swapnamay Mondal
The entropy of supersymmetric black holes in string theory compactifications can be related to that of a D- or M-brane system, which in many cases can be further reduced to a two-d…
