Krein空间中的不确定原理

Uncertainty Principles in Krein Space

Sirous Homayouni, Angelo B. Mingarelli

摘要:

在Krein空间中导出了两个一般非交换自伴算子之间的测不准关系。所有这些关系都涉及一个Krein空间诱导的基本对称算子$J$,而这些广义关系中的一些涉及一个反交换子,一个交换子,和其他各种非线性函数的两个运营商的问题。因此,在希尔伯特空间上存在一类非自伴算子,使得它们的交换子的非零蕴含着一个不确定关系。所有的关系包括经典的海森堡不确定原理,如冯·诺依曼和其他人在希尔伯特空间中制定的。此外,我们还推导出克莱因空间中与算子相关的(非线性)换位子不确定关系。

英文摘要:

Uncertainty relations between two general non-commuting self-adjoint operators are derived in a Krein space. All of these relations involve a Krein space induced fundamental symmetry operator, $J$, while some of these generalized relations involve an anti-commutator, a commutator, and various other nonlinear functions of the two operators in question. As a consequence there exist classes of non-self-adjoint operators on Hilbert spaces such that the non-vanishing of their commutator implies an uncertainty relation. All relations include the classical Heisenberg uncertainty principle as formulated in Hilbert Space by Von Neumann and others. In addition, we derive an operator dependent (nonlinear) commutator uncertainty relation in Krein space.
