量子场的时空局域化

Space-Time Localisation with Quantum Fields

Marc-Thierry Jaekel, Serge Reynaud

摘要:

我们引入了与由两个光脉冲的交叉点定义的量子点的时空位置相关的可观测量。可观测的时间与能量正则共轭。无质量量子场的共形对称性首先被用来建立这些观测量的定义,然后在坐标系变换下描述它们的相对论性质。时空观测量向加速坐标系的变换背离了经典相对论定律。在量子描述中恢复了时钟速率和频率偏移的爱因斯坦定律,它们的公式提供了一个表现为量子可观测的共形度量因子。

英文摘要:

We introduce observables associated with the space-time position of a quantum point defined by the intersection of two light pulses. The time observable is canonically conjugated to the energy. Conformal symmetry of massless quantum fields is used first to build the definition of these observables and then to describe their relativistic properties under frame transformations. The transformations to accelerated frames of the space-time observables depart from the laws of classical relativity. The Einstein laws for the shifts of clock rates and frequencies are recovered in the quantum description, and their formulation provides a conformal metric factor behaving as a quantum observable.
