摘要:

非厄米PT对称哈密顿量类$H=p^2+x^2(ix)^ε$($ε\geq0$)的能量本征值是实数、正的和离散的。这些特征值的行为已经研究了小$ε$微扰。然而,到目前为止,没有其他功能的$H$已被检查扰动。本文导出了C算子的小$ε$展开式和等价的等谱Dirac-Hermite哈密顿量$h$.

英文摘要:

The energy eigenvalues of the class of non-Hermitian PT-symmetric Hamiltonians $H=p^2+x^2(ix)^ε$ ($ε\geq0$) are real, positive, and discrete. The behavior of these eigenvalues has been studied perturbatively for small $ε$. However, until now no other features of $H$ have been examined perturbatively. In this paper the small-$ε$ expansion of the C operator and the equivalent isospectral Dirac-Hermitian Hamiltonian $h$ are derived.
