论文摘要
在本文中，我们考虑了电荷不平衡的时间演变在1+1尺寸复杂的klein-gordon理论中的全球淬火后解决了负面影响。我们专注于两种类型的全局淬火，分别称为边界状态淬灭和质量淬火。我们首先研究了边界状态淬火后动态受到无质量的哈密顿量管辖的淬火。在这种情况下，可以通过评估上半平面中通量扭转场的相关器，然后施加傅立叶变换来首先获得带电不平衡解决的消极的时间演变。我们在基础晶格模型中测试我们的分析公式。我们还研究了复杂的谐波链中的质量淬灭，该谐波在淬火后根据大量的哈密顿量进化。我们认为，可以在准粒子图片的框架中理解我们的结果。
In this paper, we consider the time evolution of charge imbalance resolved negativity after a global quench in the 1+1 dimensional complex Klein-Gordon theory. We focus on two types of global quenches which are called boundary state quench and mass quench respectively. We first study the boundary state quench where the post-quench dynamic is governed by a massless Hamiltonian. In this case, the temporal evolution of charged imbalance resolved negativity can be obtained first by evaluating the correlators of the fluxed twist field in the upper half plane and then applying Fourier transformation. We numerical test our analytical formulas in the underlying lattice model. We also study the mass quench in the complex harmonic chain where the system is evolved according to a massive Hamiltonian after the quench. We argue that our results can be understood in the framework of quasi-particle picture.
