Web2 The Dirac Equation 2.1 Derivation From Scratch The Dirac Equation has to be relativistic, and so a logical place to start our derivation is equation (1). If you’re wondering where equation (1) comes from, it’s quite simple. When you think of physics, one of the rst equations that comes to mind is the incredibly famous E= mc2 (4) WebJun 1, 2024 · 1 Answer. Sorted by: 19. The Lagrangian density for a Dirac field is. L = i ψ ¯ γ μ ∂ μ ψ − m ψ ¯ ψ. The Euler-Lagrange equation reads. ∂ L ∂ ψ − ∂ ∂ x μ [ ∂ L ∂ ( ∂ μ ψ)] … dark end of the street tabs
Derivation of Dirac
WebDerivation of the Dirac equation Dirac equation nosplit words: 76 The Dirac equationcan be derived basically "directly" from the Representation theory of the Lorentz groupfor the spin halfrepresentation, this is shown for example at Physics from Symmetry by Jakob Schwichtenberg (2015)6.3 "Dirac Equation". WebAbstract: In this work we present a derivation of Dirac's equation in a curved space-time starting from a Weyl-invariant action principle in 4+K dimensions. The Weyl invariance of Dirac's equation (and of Quantum Mechanics in general) is made possible by observing that the difference between the Weyl and the Riemann scalar curvatures in a ...
