Angular Momentum, Spin and Particle Categories

2013
By use of its commutator algebra, properties of the quantum mechanical angular momentum operator are derived. The action of a magnetic field in the Hamilton operator of a single particle is considered and fundamentals of magnetism and the Aharanov–Bohm effect including experimental examples from nanoelectronics are presented.

On the spin angular momentum of mesons

Physica, 1939
Zusammenfassung Eine allgemeine Definition fu¨r den Spindrehimpuls und die Spin-momentdichte willku¨rlicher Felder wird gegeben. Angewandt auf den Fall des Meson-Feldes ergibt sich fu¨r das Gesamt-Spin moment genau der Ausdruck von Proca; jedoch trifft die Behauptung von Durandin und Erschow, dass der Zeitmittelwert dieses Momentes bei Quantisierung ...

Operators for Angular Momentum and Spin

1984
When the eigenstates for a mode, or modes, of motion in a given system form a simple sequence or ladder, these states may be interconverted by applying an operator that moves the system up or down the ladder. In Section 5.7, such operators were constructed for the states of a harmonic oscillator; in Section 5.11, step-up and step-down operators were ...

Orbital Angular Momentum and Spin

1999
We have seen that, in nonrelativistic quantum mechanics, the angular momentum operator is the generator of rotations and commutes with the Hamiltonians of rotationally invariant (i. e., spherically symmetric) systems1. It thus plays a special role for such systems. For this reason, as a preliminary to the next topic — the Coulomb potential — we present
