A fully relativistic (Lorentz covariant) description, first put forward by Paul Dirac in 1928, of the first quantized, spin one half fermion with nonzero mass. Physical notions to do with this equation include the Dirac sea, Dirac hole theory, the Klein Paradox and the fine structure of the Hydrogen spectrum.

Problem analyzing Dirac equation in an arbitrary coordinate system using geometric calculus

This question was partially inspired from the Dirac equation in spherical coordinates. For simplicity, let’s suppose I have a two variable partial differential equation initially written in a Cartes …

Error showing the invariance of Dirac equation

Error showing the invariance of Dirac equation Starting from the following equation: $$a’\Psi’(x’)-\partial' \Psi'(x')=0 \tag{1}$$ Where, $a’=a$ is a constant, $\Psi’=A_{4 \times 4}\Psi$, is a spinor …

Is Dirac equation valid only for spin-$\frac{1}{2}$ particles?

It is usually said that Dirac got his equation by looking for the square root of the 4-momentum norm (see Dirac’s coop here). The relativistic 4-momentum norm is $$(E)^2-(\mathbf{p}c)^2=(mc^2)^2 \tag{ …
