论文摘要

我们考虑了时间依赖性的热量子态方法,并引入了有效的方案,以评估由时间依赖性扰动引起的物理量变化的有效方案,这是我们先前的论文中提出的[H. Taguchi等人,物理。 Rev. B 105,125137(2022)]。在这里,我们将Kitaev模型视为例如Majorana介导的旋转转运,例如。我们证明了我们的方案评估磁场脉冲诱导的自旋振荡的效率。

We consider the time-dependent thermal pure quantum state method and introduce the efficient scheme to evaluate the change in physical quantities induced by the time-dependent perturbations, which has been proposed in our previous paper [H. Taguchi et al., Phys. Rev. B 105, 125137 (2022)]. Here, we treat the Kitaev model to consider the Majorana-mediated spin transport, as an example. We demonstrate how efficient our scheme is to evaluate spin oscillations induced by the magnetic field pulse.
