Supersymmetric SYK Model with Global Symmetry
Prithvi Narayan, Junggi Yoon
In this paper, we introduce an supersymmetric SYK model with global symmetry. We study the large expansion of the bi-local collective action of our mode…
An Action for and Hydrodynamics from the improved Large D membrane
Yogesh Dandekar, Suman Kundu, Subhajit Mazumdar +3
It has recently been demonstrated that black hole dynamics at large D is dual to the motion of a probe membrane propagating in the background of a spacetime that solves Einstein's…
Quantum information measures for restricted sets of observables
Sudip Ghosh, Suvrat Raju
We study measures of quantum information when the space spanned by the set of accessible observables is not closed under products, i.e., we consider systems where an observer may b…
Entanglement on linked boundaries in Chern-Simons theory with generic gauge groups
Siddharth Dwivedi, Vivek Kumar Singh, Saswati Dhara +3
We study the entanglement for a state on linked torus boundaries in Chern-Simons theory with a generic gauge group and present the asymptotic bounds of Rényi entropy at two di…
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…
A Complex Fermionic Tensor Model in Dimensions
Shiroman Prakash, Ritam Sinha
In this note, we study a melonic tensor model in dimensions based on three-index Dirac fermions with a four-fermion interaction. Summing the melonic diagrams at strong coupling…
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 $…
Entangled de Sitter from Stringy Axionic Bell pair I: An analysis using Bunch Davies vacuum
Sayantan Choudhury, Sudhakar Panda
In this work, we study the quantum entanglement and compute entanglement entropy in de Sitter space for a bipartite quantum field theory driven by axion originating from ${\bf Type…
Loss of locality in gravitational correlators with a large number of insertions
Sudip Ghosh, Suvrat Raju
We review lessons from the AdS/CFT correspondence that indicate that the emergence of locality in quantum gravity is contingent on considering observables with a small number of in…
Notes on Melonic Tensor Models
Sayantan Choudhury, Anshuman Dey, Indranil Halder +3
It has recently been demonstrated that the large N limit of a model of fermions charged under the global/gauge symmetry group agrees with the large limit of the SY…
Phase Transitions of a (Super) Quantum Mechanical Matrix Model with a Chemical Potential
Takehiro Azuma, Pallab Basu, Prasant Samantray
In this paper, we study the finite-temperature matrix quantum mechanics with chemical potential term linear in the single trace of U(N) matrices, via Monte Carlo simulation. In the…
Spectral Form Factor in Non-Gaussian Random Matrix Theories
Adwait Gaikwad, Ritam Sinha
We consider Random Matrix Theories with non-Gaussian potentials that have a rich phase structure in the large limit. We calculate the Spectral Form Factor (SFF) in such models…
Abelian Tensor Models on the Lattice
Soumyadeep Chaudhuri, Victor I. Giraldo-Rivera, Anosh Joseph +2
We consider a chain of Abelian Klebanov-Tarnopolsky fermionic tensor models coupled through quartic nearest-neighbor interactions. We characterize the gauge-singlet spectrum for sm…
SYK-like Tensor Models on the Lattice
Prithvi Narayan, Junggi Yoon
We study large tensor models on the lattice without disorder. We introduce techniques which can be applied to a wide class of models, and illustrate it by studying some specifi…

We have constructed a class of perturbative dynamical black hole solutions in presence of cosmological constant. We have done our calculation in large number of dimensions. The inv…
Random Matrices and Holographic Tensor Models
Chethan Krishnan, K. V. Pavan Kumar, Sambuddha Sanyal
We further explore the connection between holographic tensor models and random matrices. First, we consider the simplest non-trivial uncolored tensor model and show that the…
COSMOS-- soft Higgsotic attractors
Sayantan Choudhury
In this work, we have developed an elegant algorithm to study the cosmological consequences from a huge class of quantum field theories (i.e. superstring theory, supergravity, extr…

Alejandro Cabo-Bizet, Victor I. Giraldo-Rivera, Leopoldo A. Pando Zayas
We compute the topologically twisted index for general supersymmetric field theories on . We also discuss asymptotically magnetica…

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…
Towards a second law for Lovelock theories
Sayantani Bhattacharyya, Felix M. Haehl, Nilay Kundu +2
In classical general relativity described by Einstein-Hilbert gravity, black holes behave as thermodynamic objects. In particular, the laws of black hole mechanics can be interpret…
