WebFeb 14, 2024 · In the present spiral complexes, both 1D chains having chiral propeller type structure of pyridines around the central metal and atropisomer of biphenyl constructed a spiral structure. That is, the chiral propeller type local structure determines the chiral structure and atropisomer of the biphenyl determines the “threefold” spiral structure.

WebConfusion about Dirac mass term. In chiral basis, ψ = ( ψ L ψ R) and therefore, ψ ¯ = ψ † γ 0 = ( ψ L † ψ R †) γ 0 = ( ψ R † ψ L †). Hence, by matrix multiplication, ψ ¯ ψ = ψ R † ψ L + ψ L † ψ R. Again using chiral projection operators it can be shown that, ψ ¯ ψ = ψ ¯ R ψ L + ψ ¯ L ψ R. Therefore ...
