Photon chirality
WebJul 1, 2004 · For example in the E1–M1 interference term for photon absorption by a chiral molecule the molecular tensor T (2) =[μ][m ∗], on contraction with the isotropic tensor of rank 2 (the Kronecker delta), yields the scalar T=(μ · m ∗) – signifying that the electric and magnetic transition moments must not be orthogonal (in transitions ... Webhelicity states respectively. Hence, we have the physical interpretation for the chirality operator: The chirality or handedness is the same as the helicity operator when the particle mass is zero or it can be neglected. The operators PLand PR are commonly referred as left handed and right handed projection operators. Projection Operator Summary:
