什么因果关系?脉冲摄动的轨线分析与Copenhagen分析的差异

Which causality? Differences between the trajectory and Copenhagen analyses of an impulsive perturbation

Edward R. Floyd

摘要:

轨迹和哥本哈根表示呈现不同的预测脉冲扰动。不同的预测是由于因果关系在轨迹和哥本哈根解释中扮演的不同角色。研究了作用于无限深方势阱基态的微扰脉冲。对于这两种表示,一阶微扰计算的时间变化的能量不同。轨迹表示的能量的这种时间变化取决于波函数的微观状态。我们表明,即使在哥本哈根认识论,这两种表示预测不同的理论结果。

英文摘要:

The trajectory and Copenhagen representations render different predictions for impulse perturbations. The different predictions are due to the different roles that causality plays in the trajectory and Copenhagen interpretations. We investigate a small perturbing impulse acting on the ground state of an infinitely deep square well. For the two representations, the first-order perturbation calculations for the temporal change in energy differ. This temporal change in energy for the trajectory representation is dependent upon the microstate of the wave function. We show that even under Copenhagen epistemology, the two representations predict different theoretical results.
