标题： Stabilizer entropy in non-integrable quantum evolutions

摘要： 纠缠和稳定子熵都参与了量子多体系统中复杂行为的出现。它们之间的相互作用是可模拟性、混合、热化和典型性的复杂性的根源。在本工作中，我们研究了自旋链量子猝发后的纠缠动力学、稳定子熵以及评估它们相互作用的一个新量——反平坦度。我们发现自由费米理论在这类资源的长时间行为中显示出与随机矩阵理论值之间的差距，而非可积模型则饱和了这一差距。 显示英文摘要

摘要： Entanglement and stabilizer entropy are both involved in the onset of complex behavior in quantum many-body systems. Their interplay is at the root of complexity of simulability, scrambling, thermalization and typicality. In this work, we study the dynamics of entanglement, stabilizer entropy, and a novel quantity assessing their interplay - called anti-flatness, after a quantum quench of a spin chain. We find that free-fermion theories show a gap in the long-time behavior of these resources compared to their random matrix theory value while non-integrable models saturate it.
