http://export.arxiv.org/pdf/hep-lat/0410015 WebThe parity operator can be introduced by building the chiral projection operators: one sees that with the help of these operators one can project the chirality state of the spinor (and analogous for the right-handed component). The chiral symmetry was introduced by Feynman and Gell-Mann to account for parity violation, which was not known to ...
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∗.
