Instantons in sine-Liouville theory
Sergei Alexandrov, Raghu Mahajan, Ashoke Sen
We compute instanton corrections to the partition function of sine-Liouville (SL) theory, which provides a worldsheet description of two-dimensional string theory in a non-trivial…
All near-horizon symmetries of the Schwarzschild black hole in linearised gravity
Ankit Aggarwal, Nava Gaddam
Asymptotic symmetries are known to constrain the infrared behaviour of scattering processes in asymptotically flat spacetimes. By the same token, one expects symmetries of the blac…
Monotonicity conjecture for multi-party entanglement I
Abhijit Gadde, Shraiyance Jain, Vineeth Krishna +2
In this paper, we conjecture a monotonicity property that we call monotonicity under coarse-graining for a class of multi-partite entanglement measures. We check these properties b…
Coherent States in M-Theory: A Brane Scan using the Taub-NUT
Joydeep Chakravarty, Keshav Dasgupta, Diksha Jain +3
The Taub-NUT geometry corresponds to the Kaluza-Klein monopole solution of M-theory and on dimension reduction along the Taub-NUT circle direction it becomes the D6 brane of type I…
Entanglement and chaos near critical point in strongly coupled gauge theory
Sanjay Pant, Debanjan Karan
We perform a holographic study of the high and low temperature behaviours of logarithmic negativity (LN) and entanglement wedge cross section (EWCS) in a large strongly coupled…
JT Gravity in de Sitter Space and the Problem of Time
Kanhu Kishore Nanda, Sunil Kumar Sake, Sandip P. Trivedi
We discuss the canonical quantisation of JT gravity in de Sitter space, following earlier work by Henneaux, with particular attention to the problem of time. Choosing the dilaton a…
The free energy of the large- fermionic Chern$\unicode{x2013}$Simons theory in the 'temporal' gauge
Shiraz Minwalla, Souparna Nath, Nikhil Tanwar +1
Most of the computational evidence for the Bose$\unicode{x2013}$Fermi duality of fundamental fields coupled to Chern$\unicode{x2013}$Simons theories originates in large-…
Quantum information geometry of driven CFTs
Jan de Boer, Victor Godet, Jani Kastikainen +1
Driven quantum systems exhibit a large variety of interesting and sometimes exotic phenomena. Of particular interest are driven conformal field theories (CFTs) which describe quant…
Sparse random matrices and Gaussian ensembles with varying randomness
Takanori Anegawa, Norihiro Iizuka, Arkaprava Mukherjee +2
We study a system of qubits with a random Hamiltonian obtained by drawing coupling constants from Gaussian distributions in various ways. This results in a rich class of system…
Towards classification of holographic multi-partite entanglement measures
Abhijit Gadde, Vineeth Krishna, Trakshu Sharma
In this paper, we systematically study the measures of multi-partite entanglement with the aim of constructing those measures that can be computed in probe approximation in the hol…
Comments on 1+1d QCD with heavy adjoint quarks
Meseret Asrat
In this paper, we determine at weak coupling the non-relativistic -body Schrödinger equation that describes the low-lying color singlet bound states of two dimensional adjoint $…
Quantum Error Correction from Complexity in Brownian SYK
Vijay Balasubramanian, Arjun Kar, Cathy Li +2
We study the robustness of quantum error correction in a one-parameter ensemble of codes generated by the Brownian SYK model, where the parameter quantifies the encoding complexity…
Bound on the central charge of CFTs in large dimension
Abhijit Gadde, Mrunmay Jagadale, Shraiyance Jain +1
In this paper, we use crossing symmetry and unitarity constraints to put a lower bound on the central charge of conformal field theories in large space-time dimensions . Specifi…
Holography of information in massive gravity using Dirac brackets
Joydeep Chakravarty, Diksha Jain, Akhil Sivakumar
The principle of holography of information states that in massless gravity, it is possible to extract bulk information using asymptotic boundary operators. In our work, we study th…
