量子力学中具有实谱的非厄米算子

Non Hermitian Operators with Real Spectrum in Quantum Mechanics

João da Providência, Natália Bebiano, João Pinheiro da Providência

摘要:

例子给出的非厄米哈密顿算子,有一个真正的频谱。一些调查运营商表示的Weil-Heisenberg代数的生成元。有人认为,存在一个对合运营商$\hat J$,使汉密尔顿$\hat J$ -厄米导致明确的定义相关的正定规范允许标准的概率解释的量子力学。Poeschl-Teller哈密顿量的非厄米扩展也被考虑。构造了由相似变换得到的厄米特对应体。

英文摘要:

Examples are given of non-Hermitian Hamiltonian operators which have a real spectrum. Some of the investigated operators are expressed in terms of the generators of the Weil-Heisenberg algebra. It is argued that the existence of an involutive operator $\hat J$ which renders the Hamiltonian $\hat J$-Hermitian leads to the unambiguous definition of an associated positive definite norm allowing for the standard probabilistic interpretation of quantum mechanics. Non-Hermitian extensions of the Poeschl-Teller Hamiltonian are also considered. Hermitian counterparts obtained by similarity transformations are constructed.
