电子自旋态的经典模拟

A classical analog for the electron spin state

K. B. Wharton, R. A. Linck, C. H. Salazar-Lazaro

摘要:

尽管传统观点认为自旋1/2系统没有经典模拟,但我们引入了一组经典耦合振荡器,其解可以精确映射到任意时变磁场中不可测电子自旋状态的动态特性。虽然没有解决量子测量问题(离散结果及其相关概率),但这种新的经典模拟产生了塞曼分裂,几何相位,电子的双倍旋磁比和其他量子现象的经典物理解释。这个基于拉格朗日的模型可以用来澄清经典系统和量子系统之间的区别,也可以作为量子基础的某些方法的路标。

英文摘要:

Despite conventional wisdom that spin-1/2 systems have no classical analog, we introduce a set of classical coupled oscillators with solutions that exactly map onto the dynamics of an unmeasured electron spin state in an arbitrary, time-varying, magnetic field. While not addressing the quantum measurement problem (discrete outcomes and their associated probabilities), this new classical analog yields a classical, physical interpretation of Zeeman splitting, geometric phase, the electron's doubled gyromagnetic ratio, and other quantum phenomena. This Lagrangian-based model can be used to clarify the division between classical and quantum systems, and might also serve as a guidepost for certain approaches to quantum foundations.
