摘要：
<正>We studied the dynamic correlations of non-integrable systems with quantum many-body scar(QMBS) states generated by a ladder operator. The ladder operator's spectral function has an exact δ-function peak induced by the QMBS states. As a concrete example, we show that in the one-dimensional(1D) spin-1 Affleck–Kennedy–Lieb–Tasaki model, the spectral function of two-magnon excitations exhibits a characteristic bowtie shape composed of a δ-function resonance peak at momentum k = π and a continuum spectrum elsewhere.
