A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality).

Webfree particle in a commutative or non-commutative plane, or a vortex-antivortex system) into the Hamiltonians of the "target systems" (NCLP or a two-vortex system in their non-chiral or chiral phases) together with the mapping of the corresponding eigenstates of the symmetry generators is a development of different forms of dynamics of Dirac [57].

In physics, chirality may be found in the spin of a particle, where the handedness of the object is determined by the direction in which the particle spins. Not to be confused with helicity, which is the projection of the spin along the linear momentum of a subatomic particle, chirality is an intrinsic quantum mechanical property, like spin.
