Abstract

We simulate a relaxation process of a polaron in polymer after photoexcitation, and a new state is realized by means of proper excitation.The original lattice configuration of the polaron splits into twosymmetrical peaks, and consequently a double-well potential is formed,where the wavefunctions of electron localized in these two wells areentangled. Thus, this process provides a method to generate theSchrödinger cat state. According to the dynamical process of thelattice configuration, the relaxation time of splitting is about 150 fs.
