准厄米量子力学中唯一度规的构造:2 × 2矩阵模型中电荷算符的不存在性

Construction of a unique metric in quasi-Hermitian quantum mechanics: non-existence of the charge operator in a 2 x 2 matrix model

Miloslav Znojil, Hendrik B. Geyer

摘要:

对于一个精确可解的2 × 2矩阵模型,构造了所有符合条件的物理度量,并证明了它们都不存在关于对合电荷算子C的因式分解CP.简要讨论了将物理度量限制为唯一形式的替代方法。

英文摘要:

For a specific exactly solvable 2 by 2 matrix model with a PT-symmetric Hamiltonian possessing a real spectrum, we construct all the eligible physical metrics and show that none of them admits a factorization CP in terms of an involutive charge operator C. Alternative ways of restricting the physical metric to a unique form are briefly discussed.
