Spectral Form Factor of Gapped Random Matrix Systems
Krishan Saraswat
In this work, we study the spectral form factor of random matrix models which exhibit a large number of degenerate ground states accompanied by a macroscopic gap in the spectrum. T…
Weil-Petersson volumes for extended JT supergravity from ordinary differential equations
Wasif Ahmed, Clifford V. Johnson, Krishan Saraswat
Recent work [1] produced an efficient method for computing Weil-Petersson volumes using two ordinary differential equations (ODEs) that appear naturally in double scaled random mat…
Constraints from Entanglement Wedge Nesting for Holography at a Finite Cutoff
Krishan Saraswat
We explore constraints that arise from associating an entanglement wedge (EW) to subregions of a cutoff boundary at a finite distance in AdS/CFT, using a subcritical end-of-the-wor…
Spacing Statistics of Energy Spectra: Random Matrices, Black Hole Thermalization, and Echoes
Krishan Saraswat, Niayesh Afshordi
Recent advances in AdS/CFT holography have suggested that the near-horizon dynamics of black holes can be described by random matrix systems. We study how the energy spectrum of a…
Extracting Hawking Radiation Near the Horizon of AdS Black Holes
Krishan Saraswat, Niayesh Afshordi
We study how the evaporation rate of spherically symmetric black holes is affected through the extraction of radiation close to the horizon. We adopt a model of extraction that inv…
Quantum Nature of Black Holes: Fast Scrambling versus Echoes
Krishan Saraswat, Niayesh Afshordi
Two seemingly distinct notions regarding black holes have captured the imagination of theoretical physicists over the past decade: First, black holes are conjectured to be fast scr…
Positive gravitational subsystem energies from CFT cone relative entropies
Dominik Neuenfeld, Krishan Saraswat, Mark Van Raamsdonk
The positivity of relative entropy for spatial subsystems in a holographic CFT implies the positivity of certain quantities in the dual gravitational theory. In this note, we consi…
