Entanglement in interacting quenched two-body coupled oscillator system
Sayantan Choudhury, Rakshit Mandish Gharat, Saptarshi Mandal +3
In this work, we explore the effects of a quantum quench on the entanglement measures of a two-body coupled oscillator system having quartic interaction. We use the invariant opera…
Krylov Complexity in Quantum Field Theory
Kiran Adhikari, Sayantan Choudhury, Abhishek Roy
In this paper, we study the Krylov complexity in quantum field theory and make a connection with the holographic "Complexity equals Volume" conjecture. When Krylov basis matches wi…
Causality Constraint on Circuit Complexity from
Sayantan Choudhury, Arghya Mukherjee, Nilesh Pandey +1
In this article, we investigate the physical implications of the causality constraint via effective sound speed on Quantum Circuit Complexity(QCC) in the framework of…
Circuit Complexity in
Kiran Adhikari, Sayantan Choudhury, Sourabh Kumar +6
Motivated by recent studies of circuit complexity in weakly interacting scalar field theory, we explore the computation of circuit complexity in Even Effective Fiel…
Semiclassical limit of topological Rényi entropy in Chern-Simons theory
Siddharth Dwivedi, Vivek Kumar Singh, Abhishek Roy
We study the multi-boundary entanglement structure of the state associated with the torus link complement in the set-up of three-dimensional SU(2) Cher…
