Representações da Equação de Dirac em 1+1 Dimensões

Abstract: Neste trabalho descrevemos uma classificação geral das representações da equação de Dirac em 1+1 dimensões. Na classificação são incluídas as representações nas quais cada matriz de Dirac β, α é associada a uma única matriz de Pauli. Esta classificação inclui 6 representações principais. A inclusão das representações com sinais modificados das matrizes de Pauli aumenta o número de representações distintas até 24. Determinamos as transformações unitárias entre todas as representações na forma explícita. O estud… Show more

“…In addition to (i ), the Weyl (or chiral or spinor) representation, {γ 0 , γ1 } = {σ x , −iσ y } (with the Dirac wave function in Eq. ( 9) written as Ψ ≡ [ ϕ 1 ϕ 2 ] T ), we must consider three other representations in (1+1) dimensions, namely, (ii ) the Dirac (or standard or Dirac-Pauli) representation, [19][20][21]. In the next section, we present some connections between these representations, i.e., the connections between the Dirac matrices and the two-component wave functions in two different representations.…”
