Probing Entanglement and Symmetries in Random States Using a Superconducting Quantum Processor
Jia-Nan Yang, Lata Kh Joshi, Filiberto Ares +3
Quantum many-body systems display an extraordinary degree of complexity, yet many of their features are universal: they depend not on microscopic details, but on a few fundamental…
Bounded-Error Quantum Simulation via Hamiltonian and Lindbladian Learning
Tristan Kraft, Manoj K. Joshi, William Lam +11
Analog Quantum Simulators offer a route to exploring strongly correlated many-body dynamics beyond classical computation, but their predictive power remains limited by the absence…
Measuring full counting statistics in a trapped-ion quantum simulator
Lata Kh Joshi, Filiberto Ares, Manoj K. Joshi +2
In quantum mechanics, the probability distribution function (PDF) and full counting statistics (FCS) play a fundamental role in characterizing the fluctuations of quantum observabl…
Observing the quantum Mpemba effect in quantum simulations
Lata Kh Joshi, Johannes Franke, Aniket Rath +9
The non-equilibrium physics of many-body quantum systems harbors various unconventional phenomena. In this study, we experimentally investigate one of the most puzzling of these ph…
Experimental Measurement of Out-of-Time-Ordered Correlators at Finite Temperature
Alaina M. Green, A. Elben, C. Huerta Alderete +6
Out-of-time-ordered correlators (OTOCs) are a key observable in a wide range of interconnected fields including many-body physics, quantum information science, and quantum gravity.…
Quantum Information Scrambling: From Holography to Quantum Simulators
Arpan Bhattacharyya, Lata Kh Joshi, Bhuvanesh Sundar
In this review, we present the ongoing developments in bridging the gap between holography and experiments. To this end, we discuss information scrambling and models of quantum tel…
Proposal for measuring out-of-time-ordered correlators at finite temperature with coupled spin chains
Bhuvanesh Sundar, Andreas Elben, Lata Kh Joshi +1
Information scrambling, which is the spread of local information through a system's many-body degrees of freedom, is an intrinsic feature of many-body dynamics. In quantum systems,…
Probing many-body quantum chaos with quantum simulators
Lata Kh Joshi, Andreas Elben, Amit Vikram +3
The spectral form factor (SFF), characterizing statistics of energy eigenvalues, is a key diagnostic of many-body quantum chaos. In addition, partial spectral form factors (PSFFs)…
Time-dependent holography with applications
Lata Kh Joshi, Ayan Mukhopadhyay, Alexander Soloviev
We develop a method for obtaining exact time-dependent solutions in Jackiw-Teitelboim gravity coupled to non-conformal matter and study consequences for holography. We stu…
Gravitational collapse in SYK models and Choptuik-like phenomenon
Avinash Dhar, Adwait Gaikwad, Lata Kh Joshi +2
SYK model is a quantum mechanical model of fermions which is solvable at strong coupling and plays an important role as perhaps the simplest holographic model of quantum gravity an…
Holographic dual to charged SYK from 3D Gravity and Chern-Simons
Adwait Gaikwad, Lata Kh Joshi, Gautam Mandal +1
In this paper, we obtain a bulk dual to SYK model, including SYK model with charge, by Kaluza-Klein (KK) reduction from three dimensions. We show that KK reduction of the 3D…
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…
Exact time dependence of causal correlations and nonequilibrium density matrices in holographic systems
Lata Kh Joshi, Ayan Mukhopadhyay, Florian Preis +1
We present the first exact calculations of the time dependence of causal correlations in driven nonequilibrium states in (2+1)-dimensional systems using holography. Comparing exact…
Analytic corrections to AdS by scalar matter and curvature squared term

We revisit the background solution for scalar matter coupled higher derivative gravity originally reported in arXiv: 1409.8019[hep-th]. In this letter, we choose a convenient ansat…
Time-dependence of the holographic spectral function: Diverse routes to thermalisation
Souvik Banerjee, Takaaki Ishii, Lata Kh Joshi +2
We develop a new method for computing the holographic retarded propagator in generic (non-)equilibrium states using the state/geometry map. We check that our method reproduces the…
Backreaction effects due to matter coupled higher derivative gravity
Lata Kh Joshi, P. Ramadevi
AdS-hydrodynamics has proven to be a useful tool for obtaining transport coefficients observed in the collective flow of strongly coupled fluids like quark gluon plasma (QGP). Part…
