A finite-frequency fluctuation-response inequality bounds the measured lock-in response-to-noise matrix by the output-field quantum Fisher information rate for Markovian open quantum systems.
LR-TDDFT analysis of the self-enhancement function classifies coherent versus incoherent magnons in Fe, Ni, and Co, revealing branch coexistence in bcc-Fe and decoherence near the Brillouin zone boundary in fcc-Ni while defining the many-body Stoner spectrum.
