能量相关的哈密顿量及其伪厄米解释

Energy-dependent Hamiltonians and their pseudo-Hermitian interpretation

Miloslav Znojil, Hynek Bila, Vit Jakubsky

摘要:

重新分析了量子力学中的能量相关力概念。我们建议简化他们的研究,通过表示每个自伴和能量相关的哈密顿量H=H(E)与实谱的一个辅助的非厄米算子K,保持能量无关。这种方法的实用价值的薛定谔方程与能量相关的潜力说明使用其准精确可解的例子。

英文摘要:

The concept of energy-dependent forces in quantum mechanics is re-analysed. We suggest a simplification of their study via the representation of each self-adjoint and energy-dependent Hamiltonian H=H(E) with real spectrum by an auxiliary non-Hermitian operator K which remains energy-independent. Practical merits of such an approach to the Schroedinger equations with energy-dependent potentials are illustrated using their quasi-exactly solvable example.
