论文摘要
结果表明，在Loschmidt速率奇点中观察到的奇异性的动力学量子相变与从两级系统的动力学中知道的标准RABI振荡非常相似。对于某些多体系统，这种类比可能会进一步发展，并且观察到的行为为例如横向式链可以直接映射到如此简单的动力学。解释了为什么提出了Loschmidt Echo奇点和量子疤痕之间的简单联系。
It is shown that dynamical quantum phase transitions observed as singularities in the Loschmidt rate singularities bear close resemblance to standard Rabi oscillations known from dynamics of two-level systems. For some many-body systems this analogy may go even further and the behaviour observed for e.g. transverse Ising chain can be directly mapped to such simple dynamics. It is explained why A simple link between Loschmidt echo singularities and quantum scars is suggested.
