Plane Wave Solutions To The Dirac Equation Relativistic Quantum The dirac equation. the dirac equation. our goal is to find the analog of the schrödinger equation for relativistic spin one half particles, however, we should note that even in the schrödinger equation, the interaction of the field with spin was rather ad hoc. there was no explanation of the gyromagnetic ratio of 2. This is the free particle schr¨odinger equation, and it is the basis of non relativistic quantum mechanics. its solutions ψ(~x,t) describe the states of matter. a plethora of experiments in many diverse contexts have validated (se), and much of modern technology is based on the quantum mechanical theory of which it is the basis. Start from the dirac equation and attempt to develop an equation to show that each component has the free particle exponential. we will do this by making a second order differential equation, which turns out to be the klein gordon equation. the free electron solutions all satisfy the wave equation. because we have eliminated the matrices from. Theory of free particle solutions of the dirac equation than it does in the pauli theory. 4. free particle solutionsof the dirac equation at rest there are four linearly independent solutions of the time dependent dirac equation for a free particle at rest. these are given in eq. (46.31), reproduced here: 1 0 0 0 e−imc 2t ¯h, 0 1 0 0.
