Robustness of quantum symmetries against perturbations
arXiv:2411.18529 · doi:10.1088/1751-8121/adbfe5
Abstract
We investigate quantum symmetries in terms of their large-time stability with respect to perturbations of the Hamiltonian. We find a complete algebraic characterization of the set of symmetries robust against a single perturbation and we use such result to characterize their stability with respect to arbitrary sets of perturbations.
