离散PT对称方阱哈密顿量的内积完备集

Complete Set of Inner Products for a Discrete PT-symmetric Square-well Hamiltonian

Miloslav Znojil

摘要:

研究了一种最简单的非厄米方阱实谱哈密顿量的离散$N-$点龙格库塔形式$H^{(N)}(λ)$。一组完整的可能的厄米化(即,对于任何耦合$λ\in (-1,1)$和任何矩阵维数$N$,以封闭形式构造定义其非等价物理希尔伯特状态空间的合格度量$Θ^{(N)}(λ)$)。

英文摘要:

A discrete $N-$point Runge-Kutta version $H^{(N)}(λ)$ of one of the simplest non-Hermitian square-well Hamiltonians with real spectrum is studied. A complete set of its possible hermitizations (i.e., of the eligible metrics $Θ^{(N)}(λ)$ defining its non-equivalent physical Hilbert spaces of states) is constructed, in closed form, for any coupling $λ\in (-1,1)$ and any matrix dimension $N$.
