WebTwo of authors of this paper showed any chiral symmetric unitary operator has a spectral mapping property from a self-adoint operator by the Joukowsky transform (divided by two) [34,35]. More precisely, a bounded operator uis said to have chiral symmetry if there exists a unitary involution γ, i.e., γ−1 = γ∗ = γ, such that γuγ∗ = u∗. WebLet's have chirality projection operator $$ \hat {C}_{\pm} = \frac{1 \pm \gamma^{5}}{2}. $$ We introduce it and called it chirality, because $$ \hat {C}_{+}\psi = \begin{pmatrix} …
