论文摘要

Frisch和Segrè进行的多阶段船尾$ \ Unicode {X2013} $ Gerlach实验包括两个层次的量子测量,并在两者之间进行非绝热的脚。 Frisch和Segrè实验已通过Majorana对没有核效应进行分析模型,随后由Rabi通过超细相互作用进行了修订。但是,理论预测与实验观察不符。在这里,我们通过von Neumann方程来数值求解标准的量子机械模型,包括自旋时间演变的超精细相互作用。到目前为止,在不使用自由参数的情况下,从标准量子机械模型中确定的系数仍然很低,这表明理论与实验之间的不匹配。探索了改进比赛的非标准变体进行讨论。

The multi-stage Stern$\unicode{x2013}$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.
