Dynamical scaling symmetry and asymptotic quantum correlations for time-dependent scalar fields

SM Chandran, S Shankaranarayanan - Physical Review D, 2023 - APS
In time-independent quantum systems, entanglement entropy possesses an inherent scaling
symmetry that the energy of the system does not have. The symmetry also assures that …
