作为自由粒子可能运动的数学描述的波函数:尝试探测的2缝问题

The wave function as a mathematical description of a free particle's possible motion: The 2-slit problem with attempted detection

Thomas O'Malley

摘要:

从一个脚踏实地的解释量子力学为一个自由粒子,消失和再现的干涉在2缝问题与后面的一个检测器进行了详细的处理。部分解释的量子理论是简单的,强调描述,但足以解决目前的问题。鉴于本征值方程是必不可少的预测一个自由粒子的碰撞概率,有人认为,有一个现实的理论来描述其可能的运动是平等的需要。提出了Feynman的点到点时空波包,并将其作为碰撞间无场运动的恰当描述。对于一个粒子在一个传统的双缝实验与尝试检测后,解释了干涉的消失-无论是当检测成功,当它没有。当狭缝间距离减小时,还对干涉的第一个迹象应该出现在检测屏幕上的位置进行了明确的预测。

英文摘要:

Starting with a down to earth interpretation of quantum mechanics for a free particle, the disappearance and reappearance of interference in the 2 slit problem with a detector behind one are treated in detail. A partial interpretation of quantum theory is employed which is simple, emphasizing description, yet adequate for addressing the present problem. Given that the eigenvalue equation is essential to predict a free particle's probability of collision, it is argued that there is equal need for a realistic theory to describe its possible motion. Feynman's point-to-point space-time wave packet is put forth and used as the appropriate description of the field-free motion between collisions. For a particle in a conventional 2-slit experiment with attempted detection behind one, the disappearance of interference is explained - both when the detection succeeds and when it doesn't. Also a definite prediction is made, when the inter-slit distance is reduced, of where the first signs of interference should appear on the detection screen.
