Quantum Chaos and Holographic Tensor Models
Chethan Krishnan, Sambuddha Sanyal, P. N. Bala Subramanian
A class of tensor models were recently outlined as potentially calculable examples of holography: their perturbative large- behavior is similar to the Sachdev-Ye-Kitaev (SYK) mo…
A Dynamical Boundary for Anti-de Sitter Space
Chethan Krishnan, Avinash Raju, P. N. Bala Subramanian
We argue that a natural boundary condition for gravity in asymptotically AdS spaces is to hold the {\em renormalized} boundary stress tensor density fixed, instead of the boundary…
Hairy Black Holes in a Box
Pallab Basu, Chethan Krishnan, P. N. Bala Subramanian
We do a systematic study of the phases of gravity coupled to an electromagnetic field and charged scalar in flat space, with box boundary conditions. The scalar-less box has previo…
BRST Symmetry: Boundary Conditions and Edge States in QED
Nirmalendu Acharyya, A. P. Balachandran, Verónica Errasti Díez +2
In manifolds with spatial boundary, BRST formalism can be used to quantize gauge theories. We show that, in a gauge theory, only a subset of all the boundary conditions allo…
Phases of Global AdS Black Holes
Pallab Basu, Chethan Krishnan, P. N. Bala Subramanian
We study the phases of gravity coupled to a charged scalar and gauge field in an asymptotically Anti-de Sitter spacetime () in the grand canonical ensemble. For the conforma…
