WebDec 30, 2024 · Using P = ( ℏ / i) ∇, in the coordinate basis, the Dirac equation for a free particle reads. Since the operator on the left side is a 4 × 4 matrix, the wave function Ψ ( r, … Webwhere the diagonal matrix ημν has diagonal elements 1,−1,−1,−1, and I4 is the unit 4× 4 matrix. The Einstein summation convention is used for repeated indices in equations, with … In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. In its free form, or including electromagnetic interactions, it describes all spin-1⁄2 massive particles, called "Dirac particles", such as electrons and quarks for which parity is a symmetry. It is consistent with both the principles of quantum mechanics and the theory of special relativity, and was the first theory to account fully for special relativity in the context of quantum … how do you treat swim bladder in fish
