Optical Susceptibilities of Polymers: Current-Current versus Dipole-Dipole Correlation
Xu, Minzhong · Sun, Xin
Original · EN
The static current operator leads to definitional zero frequency divergence and unphysical results in studying nonlinear optical susceptibilities of polymers. A well-defined dipole-dipole correlation is superior to the complicated current-current correlation to solve this problem. As illustrative examples, optical susceptibilities under both SSH and TLM models of trans-(CH)ₓ are studied. New analytical results are obtained. The reasons of previous improper results are analyzed.
