Commutation of Spin, Angular and Spin-Orbital Momentum

Saturday, March 20th, 2010

Marichu T. Miscala In quantum mechanics, the presence of spin-orbit coupling gives rise to the Hamiltonian that will no longer commute with [eq]\vec{L}[/eq], and [eq]\vec{S}[/eq], so the spin and orbital momenta are not separately conserved. In order to understand this concept better,¬†a¬†commutation problem for orbital angular momentum [eq]\vec{L}[/eq], spin [eq]\vec{S}[/eq], and spin-orbital momentum [eq]\vec{J}[/eq] is […]

BELL’S INEQUALITY: A Distinction between Local Reality and Quantum Mechanics Theory

Saturday, February 27th, 2010

Marichu M. Tompong-Miscala Local realism is the idea that an object has definite properties or assumes a definite state without being affected by the act of measurement [1]. This belief is especially contrary to the probabilistic ( not deterministic ) characteristic of quantum mechanics. In 1965, John S. Bell had proposed a mathematical proof or […]
