论文摘要
在目前的工作中,我们提出了在奇偶校验和时间上的隧道时间的概括($ \ MATHCAL {P} \ MATHCAL {T} $) - 对称系统。使用简单的触点交互研究了$ \ Mathcal {p} \ Mathcal {t} $ - 对称系统中的隧道时间的属性。讨论了$ \ Mathcal {P} \ Mathcal {T} $ - 对称系统及其与光谱奇点的关系的物理含义。
In the present work we propose a generalization of tunneling time in parity and time ($\mathcal{P}\mathcal{T}$)-symmetric systems. The properties of tunneling time in $\mathcal{P}\mathcal{T}$-symmetric systems are studied with a simple contact interactions periodic finite size diatomic $\mathcal{P}\mathcal{T}$-symmetric model. The physical meaning of negative tunneling time in $\mathcal{P}\mathcal{T}$-symmetric systems and its relation to spectral singularities is discussed.
