Emergence of states in a quantum impurity model
arXiv:2501.13914 · doi:10.1103/PhysRevResearch.7.L022027
Abstract
In the present work, we demonstrate the emergence of states in the long-time response of a locally perturbed many-body quantum impurity model. The emergence of the double-qubit state is heralded by the lack of decay of the response function as well as the out-of-time order correlator, signifying the trapping of excitations and hence information in edge modes. Surprisingly, after carrying out a quantum information theory characterization, we show that such states exhibit genuine quantum correlations.
