Graph Symmetry Organizes Exceptional Dynamics in Open Quantum Systems

2026-06-11

Abstract excerpt

<title>Abstract</title> <p>Exceptional points (EPs), indicative of parity–time (PT) symmetry breaking, play a central role in non-Hermitian physics, yet most studies begin from deliberately engineered effective Hamiltonians whose parameters are tuned to exhibit exceptional behaviour.In realistic open quantum systems, however, dynamics are governed by Lindblad superoperators whose spectral structure is high-dimens...
