Approximate CFTs and Random Tensor Models
Alexandre Belin, Jan de Boer, Daniel Louis Jafferis +2
A key issue in both the field of quantum chaos and quantum gravity is an effective description of chaotic conformal field theories (CFTs), that is CFTs that have a quantum ergodic…
Generalized Spectral Form Factors and the Statistics of Heavy Operators
Alexandre Belin, Jan de Boer, Pranjal Nayak +1
The spectral form factor is a powerful probe of quantum chaos that diagnoses the statistics of energy levels, but is blind to other features of a theory such as matrix elements of…
From operator statistics to wormholes
Alexander Altland, Dmitry Bagrets, Pranjal Nayak +2
For a generic quantum many-body system, the quantum ergodic regime is defined as the limit in which the spectrum of the system resembles that of a random matrix theory (RMT) in the…
Charged Eigenstate Thermalization, Euclidean Wormholes and Global Symmetries in Quantum Gravity
Alexandre Belin, Jan de Boer, Pranjal Nayak +1
We generalize the eigenstate thermalization hypothesis to systems with global symmetries. We present two versions, one with microscopic charge conservation and one with exponential…
Extended Eigenstate Thermalization and the role of FZZT branes in the Schwarzian theory
Pranjal Nayak, Julian Sonner, Manuel Vielma
In this paper we provide a universal description of the behavior of the basic operators of the Schwarzian theory in pure states. When the pure states are energy eigenstates, expect…
Correlation functions in Supersymmetric vector matter Chern-Simons theory
Karthik Inbasekar, Sachin Jain, Vinay Malvimat +3
We compute the two, three point function of the opearators in the spin zero multiplet of Supersymmetric vector matter Chern-Simons theory at large and at all order…
Eigenstate Thermalisation in the conformal Sachdev-Ye-Kitaev model: an analytic approach
Pranjal Nayak, Julian Sonner, Manuel Vielma
The Sachdev-Ye-Kitaev (SYK) model provides an uncommon example of a chaotic theory that can be analysed analytically. In the deep infrared limit, the original model has an emergent…
On the Dynamics of Near-Extremal Black Holes
Pranjal Nayak, Ashish Shukla, Ronak M Soni +2
We analyse the dynamics of near-extremal Reissner-Nordström black holes in asymptotically four-dimensional Anti-de Sitter space (AdS). We work in the spherically symmetric appr…
Dual Superconformal Symmetry of Chern-Simons theory with Fundamental Matter at Large
Karthik Inbasekar, Sachin Jain, Sucheta Majumdar +5
Dual conformal symmetry and Yangian symmetry are symmetries of amplitudes that have aided the study of scattering amplitudes in highly supersymmetric theories like SYM…
All tree level scattering amplitudes in Chern-Simons theories with fundamental matter
Karthik Inbasekar, Sachin Jain, Pranjal Nayak +1
We show that Britto-Cachazo-Feng-Witten (BCFW) recursion relations can be used to compute all tree level scattering amplitudes in terms of scattering amplitude in $…
A Note on S-Matrix Bootstrap for Amplitudes with Linear Spectrum
Pranjal Nayak, Rohan R. Poojary, Ronak M Soni
We work out constraints imposed by channel duality and analyticity on tree-level amplitudes of four identical real scalars, with the assumptions of a linear spectrum of exchanged p…
Coadjoint orbit action of Virasoro group and two-dimensional quantum gravity dual to SYK/tensor models
Gautam Mandal, Pranjal Nayak, Spenta R. Wadia
The Nambu-Goldstone (NG) bosons of the SYK model are described by a coset space Diff/, where Diff, or Virasoro group, is the group of diffeomorphisms of…
Revisiting AdS/CFT at a finite radial cut-off
Gautam Mandal, Pranjal Nayak
We revisit AdS/CFT at finite radial cut-off, specifically in the context of double trace perturbations, = , with arbit…
