相对论量子力学的Foldy-Wouthuysen变换与半经典跃迁

Foldy-Wouthuysen Transformation and Semiclassical Transition for Relativistic Quantum Mechanics

Alexander J. Silenko

摘要:

结果表明,强外场中相对论性粒子的Foldy-Wouthuysen变换提供了获得相对论性量子力学有意义的经典极限的可能性.证明了量子理论与经典理论的完全一致性。建立了粒子及其自旋的半经典运动方程与相应的经典方程的重合性。Niels Bohr的对应原理不仅在大自旋量子数的极限下成立,而且对任意自旋粒子和无自旋粒子都成立。

英文摘要:

It is shown that the Foldy-Wouthuysen transformation for relativistic particles in strong external fields provides the possibility of obtaining a meaningful classical limit of the relativistic quantum mechanics. The full agreement between quantum and classical theories is proved. The coincidence of the semiclassical equations of motion of particles and their spins with the corresponding classical equations is established. The Niels Bohr's correspondence principle is valid not only in the limit of large spin quantum numbers but also for particles with any spin as well as for spinless particles.
