论文摘要
在工作\ cite {vergeles2021note}中显示的是，在重力理论与狄拉克场的理论中，每个状态$ |λ\ rangle $都有其自己的twin $ |λ; pt \ rangle $，这是由离散的PT转换获得的。如果在州$ |λ\ rangle $ $ dirac Sea已填充，则在状态$ |λ; pt \ rangle $中有一个“反迪拉克”填充（就状态$ |λ\ rangle $而言）。重要的是，这些状态的能量是相同的。因此，可能会有一些域中填充狄拉克海的域。在这里，我们研究了连接两个此类相邻域的域壁。
It was shown in work \cite{vergeles2021note} that in the theory of gravity coupled with the Dirac field, each state $|λ\rangle$ has its own twin $|λ;PT\rangle$, which is obtained by a discrete PT transformation. If in the state $|λ\rangle$ the Dirac sea is filled, then in the state $|λ;PT\rangle$ there is an "anti-Dirac" filling (in terms of the state $|λ\rangle$). It is important that the energies of these states are the same. Therefore, there may be domains with different filling of the Dirac sea. Here we study a domain wall connecting two such adjacent domains.
