李代数框架下实特征值和复特征值的非厄米哈密顿量

Non-Hermitian Hamiltonians with real and complex eigenvalues in a Lie-algebraic framework

B. Bagchi, C. Quesne

摘要:

我们表明,复杂的李代数(特别是sl(2,C))为我们提供了一个优雅的方法,研究从实到复的一类非厄米哈密顿特征值的过渡:复杂的围巾II,广义Pöschl-Teller,莫尔斯。在所谓的伪厄米性下,这些哈密顿量的特征也进行了讨论。

英文摘要:

We show that complex Lie algebras (in particular sl(2,C)) provide us with an elegant method for studying the transition from real to complex eigenvalues of a class of non-Hermitian Hamiltonians: complexified Scarf II, generalized Pöschl-Teller, and Morse. The characterizations of these Hamiltonians under the so-called pseudo-Hermiticity are also discussed.
