摘要

弗里施和塞格雷进行的多级斯特恩-格拉赫实验包括两个级联量子测量,中间有一个非绝热翻转器。马约拉纳对弗里施和塞格雷实验进行了不含核效应的分析建模,随后拉比对其进行了超精细相互作用的修正。然而,理论预测与实验观测并不完全吻合。在这里,我们通过冯-诺依曼方程对标准量子力学模型进行数值求解,包括自旋时间演化的超细相互作用。到目前为止,不使用自由参数的标准量子力学模型的确定系数仍然很低,这表明理论与实验之间存在不匹配。我们探讨了能改善匹配的非标准变体,以供讨论。

Quantum mechanical modeling of the multi-stage Stern–Gerlach experiment conducted by Frisch and Segrè
The multi-stage Stern–Gerlach experiment conducted by Frisch and Segrè includes two cascaded quantum measurements with a nonadiabatic flipper in between. The Frisch and Segrè experiment has been modeled analytically by Majorana without the nuclear effect and subsequently revised by Rabi with the hyperfine interaction. However, the theoretical predictions do not match the experimental observation accurately. Here, we numerically solve the standard quantum mechanical model, via the von Neumann equation, including the hyperfine interaction for the time evolution of the spin. Thus far, the coefficients of determination from the standard quantum mechanical model without using free parameters are still low, indicating a mismatch between the theory and the experiment. Non-standard variants that improve the match are explored for discussion.
