量子理论中Hilbert空间的时间相关和/或非定域表示

Time-Dependent and/or Nonlocal Representations of Hilbert Spaces in Quantum Theory

Miloslav Znojil

摘要:

本文评述了近年来量子理论标准教材在适用性方面的一些创新。理论的三希尔伯特空间表述(从核物理中的相互作用玻色子模型中得知)在其稍微扩大的四希尔伯特空间更新中进行了讨论。在涉及几个新的散射和束缚态问题的应用程序中,发挥核心作用的模型显然使用非厄米(“隐厄米”)的哈密顿与真正的频谱。的形式主义(最初的灵感来自局部需要的数学上一致的描述tobogganic量子模型)被证明承认某些不寻常的非本地和/或“移动框架”表示的标准物理希尔伯特空间的波函数。

英文摘要:

A few recent innovations of applicability of standard textbook Quantum Theory are reviewed. The three-Hilbert-space formulation of the theory (known from the interacting boson models in nuclear physics) is discussed in its slightly broadened four-Hilbert-space update. Among applications involving several new scattering and bound-state problems the central role is played by the models using apparently non-Hermitian ("crypto-Hermitian") Hamiltonians with real spectra. The formalism (originally inspired by the topical need of mathematically consistent description of tobogganic quantum models) is shown to admit certain unusual nonlocal and/or "moving-frame" representations of the standard physical Hilbert space of wave functions.
