We all learn in elementary quantum mechanics class that all measurable physical quantities, and specifically the Hamiltonian operator, must be Hermitian, because the eigenvalues must be real. This is perhaps von Neumann’s mathematical dogma, to which two main physical counterarguements exist.

社论：非赫米特量子力学

我们都在基本量子力学课程中学习到，所有可测量的物理量，尤其是哈密顿算子，必须是埃尔米特数，因为特征值必须是实数。这也许是冯·诺依曼的数学教条，对此存在两个主要的物理反驳。
