A general scheme extracts real-space order parameters from dominant Fock-state patterns in many-body ground states, revealing sub-structures within topological sectors and diagnosing BKT transitions.
Nonadiabatic modulation near a quantum critical point strongly boosts photon emission from vacuum fluctuations, enhancing flux and non-classical properties even against thermal noise.
Interference between local measurement histories on two qubits generates entanglement, persisting even after averaging over detector readouts.
