Circuit Complexity in Interacting Quenched Quantum Field Theory

S Choudhury, RM Gharat, S Mandal, N Pandey - Symmetry, 2023 - mdpi.com
In this work, we explore the effects of quantum quenching on the circuit complexity of
quenched quantum field theory with weakly coupled quartic interactions. We use the …

Entanglement in interacting quenched two-body coupled oscillator system

S Choudhury, RM Gharat, S Mandal, N Pandey, A Roy… - Physical Review D, 2022 - APS
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 operator …

Properties of modular Hamiltonians on entanglement plateaux

R Abt, J Erdmenger - Journal of High Energy Physics, 2018 - Springer
A bstract The modular Hamiltonian of reduced states, given essentially by the logarithm of
the reduced density matrix, plays an important role within the AdS/CFT correspondence in …

Implementing Aspects of Quantum Information into the AdS/CFT Correspondence

R Abt - 2019 - opus.bibliothek.uni-wuerzburg.de
In recent years many discoveries have been made that reveal a close relation between
quantum information and geometry in the context of the AdS/CFT correspondence. In this …
