Covariant and hermitian semi-classical limit of quantum dynamical equations for spin-1/2 particles

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The Dirac equation—with a Pauli term—is transformed to a covariant and Hermitian two-component form to first order inħ. The Bargmann-Michel-Telegdi equations are deduced as equations of motion for spin operators. Corresponding operators in the Dirac and the semi-classical picture are discussed.

Riassunto

Si trasforma l’equazione di Dirac — con un termine di Pauli — in una forma covariante e hermitiana a due componenti, del primo ordine inħ. Si deducono le equazioni di Bargmann-Michel-Teledgi come equazioni di moto degli operatori di spin. Si discutono i corrispondenti operatori nella rappresentazione di Dirac ed in quella semiclassica.
