Há 4 dias · 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 .

21 de mai. de 2024 · The Dirac Equation, formulated by British physicist Paul Dirac in 1928, is a fundamental equation in quantum mechanics that describes the behavior of fermions, such as electrons. This relativistic wave equation merges quantum mechanics and special relativity, predicting the existence of antimatter and explaining the intrinsic spin of ...
10 de mai. de 2024 · The Dirac equation. To tackle the problems with the Klein-Gordon equation, Dirac formulated the now-famous. Dirac equation ( DE) ˆEψ = (α ⋅ ˆp + βm)ψ. Expressed with operators ˆE = i ∂ ∂t and ˆp = − i∇, the equation takes form. i∂ψ ∂t = − iαx∂ψ ∂x − iαy∂ψ ∂y − iαz∂ψ ∂z + βmψ. From the equation above we form equation.
13 de mai. de 2024 · Among other discoveries, he formulated the Dirac equation, which describes the behavior of fermions and which led to the prediction of the existence of antimatter. Dirac shared the Nobel Prize in physics for 1933 with Erwin Schrödinger, “for the discovery of new productive forms of atomic theory.”.
5 de mai. de 2024 · Dirac’s equation is a relativistic wave equation explaining that parity inversion (sign inversion of spatial coordinates) is symmetrical for all half-spin electrons and quarks. The equation was first explained in 1928 by P. A. M. Dirac. The equation is used to predict the existence of antiparticles.
Há 1 dia · in which the γ = (γ 1, γ 2, γ 3) and γ 0 are the Dirac gamma matrices related to the spin of the particle. The Dirac equation is true for all spin-1 ⁄ 2 particles, and the solutions to the equation are 4-component spinor fields with two components corresponding to the particle and the other two for the antiparticle.
