相对论和非相对论量子力学中的时间

Time in relativistic and nonrelativistic quantum mechanics

H. Nikolic

摘要:

在相对论和非相对论量子力学中,运动学时间算符可以通过将时间与空间同等对待而自然地定义。时空位置算符作用在空间和时间函数的希尔伯特空间中。然而,动力学使得时间算符的本征态非物理的。这对QM的标准解释提出了一个问题,并加强了替代解释的作用,如Bohmian解释。Bohmian解释,尽管是非本地的按照贝尔定理,被证明是相对论协变的。

英文摘要:

The kinematic time operator can be naturally defined in relativistic and nonrelativistic quantum mechanics (QM) by treating time on an equal footing with space. The spacetime-position operator acts in the Hilbert space of functions of space and time. Dynamics, however, makes eigenstates of the time operator unphysical. This poses a problem for the standard interpretation of QM and reinforces the role of alternative interpretations such as the Bohmian one. The Bohmian interpretation, despite of being nonlocal in accordance with the Bell theorem, is shown to be relativistic covariant.
