Quantum Mechanics - Relativistic Quantum Mechanics : Dirac Equation

Описание к видео Quantum Mechanics - Relativistic Quantum Mechanics : Dirac Equation

In order to the difficulties faced by Klein-Gordon equation as the non-definite probability density, we follow the historical path adopted by Dirac in seeking a relativistic covariant equation linear in time and spatial derivatives. Dirac postulated a Hamiltonian linear in momentum introducing certain operators. The operators so introduced are related to some property of the particles. These operators are related to the spin of the particles and to the existence of the antiparticles (negative energy states).
