Relativistic Quantum Mechanics
... We have found that the Klein-Gordon equation, a candidate for describing the quantum mechanics of spinless particles, admits unacceptable negative energy states when is interpreted as the single particle wave function. There is another way forward (this is the way followed in the textbook of Halze ...

3.3 Why do atoms radiate light?
... • This explains too, why atoms can be stable, although they have a rotational momentum (in the classical description they would always radiate light and thus be destroyed). This classical explanation results from the wrong picture, that the electron is moving through the orbital, leading to a steady ...

QUASICLASSICAL AND QUANTUM SYSTEMS OF ANGULAR FOR QUANTUM-MECHANICAL MODELS WITH SYMMETRIES
... Presented by Jan J. Sławianowski Abstract. We use the mathematical structure of group algebras and H + -algebras for describing certain problems concerning the quantum dynamics of systems of angular momenta, including also the spin systems. The underlying groups are SU(2) and its quotient SO(3, R). ...
