Sturm-Schroedinger方程:度量公式
Sturm-Schroedinger equations: formula for metric
摘要:
本文考虑Sturm-Schroedinger方程$Hψ=E Wψ$与$H\neq H^\dagger$和$W\neq W^\dagger \neq I$,其理论的一个弱点在于物理希尔伯特状态空间中必要度规算子$Θ$的双级数定义的纯数值矩阵求逆形式[M. Znojil,J. Phys. A:Math. Theor. 41(2008)215304]。这里通过$Θ$的修正的单系列定义消除了这个缺点。
英文摘要:
Sturm-Schroedinger equations $Hψ=E Wψ$ with $H\neq H^\dagger$ and $W\neq W^\dagger \neq I$ are considered, with a weak point of the theory lying in the purely numerical matrix-inversion form of the double-series definition of the necessary metric operator $Θ$ in the physical Hilbert space of states [M. Znojil, J. Phys. A: Math. Theor. 41 (2008) 215304]. This shortcoming is removed here via an amended, single-series definition of $Θ$.
