标题： Quantum many-body scarring from Kramers-Wannier duality

摘要： 克朗默斯-瓦尼尔对偶性是伊辛模型的标志性特性，最近由于其被重新解释为具有状态级作用的不可逆对称性而再次受到关注。 使用顺序量子电路（SQC），我们认为这种对偶性决定了非可积模型中量子多体疤痕（QMBS）态的稳定性，这取决于对偶是否保持疤痕的嵌入条件。 这一结论得到了一阶微扰理论与数值模拟之间显著一致的支持，尽管存在混沌谱，它们仍能捕捉到疤痕动力学。 我们的结果表明，不可逆对偶性既为新的QMBS提供了生成机制，也为它们的稳定性提供了诊断方法。 显示英文摘要

摘要： Kramers-Wannier duality, a hallmark of the Ising model, has recently gained renewed interest through its reinterpretation as a non-invertible symmetry with a state-level action. Using sequential quantum circuits (SQC), we argue that this duality governs the stability of quantum many-body scar (QMBS) states in a nonintegrable model, depending on whether the dual preserves the embedding conditions for scarring. This is supported by striking agreement between first-order perturbation theory and numerics, which capture scar dynamics despite chaotic spectra. Our results suggest that non-invertible dualities provide both a generative mechanism for new QMBS and a diagnostic for their stability.
