WebJan 19, 2024 · Chiral symmetry provides the symmetry protection for a large class of topological edge states. It exists in non-Hermitian systems as well, and the same anticommutation relation between the Hamiltonian and a linear chiral operator, i.e., {H, Π} = 0, now warrants a symmetric spectrum about the origin of the complex energy … Weband for this reason γ 5 is called the chirality operator. Of course, all the statements derived so far are independent of the representation chosen for the γ matrices. However, there is a particular form of the γ matrices, known as the Weyl or chiral representation, that best demonstrates the chiral content of the Dirac equation.

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∗.
