Nonequilibrium quantum states emerging from flippable spins in random networks
The study investigates how irregular interaction networks in a quantum Ising spin system affect its eigenstate entanglement and dynamics. By analyzing network structures, the authors introduce 'flippability,' a measure of spin freedom, which correlates with the Hilbert space structure. This link suggests that network topology dictates whether the system thermalizes or exhibits non-thermal, scar-like quantum many-body states.
