Energy transfer simulation for a light-nanomatter composite system is proposed. The simulation based on density matrix formalism has been developed where nanomatter is represented as collection of lattice sites for creation and annihilation of dressed photon. In this paper, coarse-graining method for this system is discussed to deal with more complicated systems. The lattice model of nanomatter can be simplified by renormalizing contribution of neighboring lattice sites into coupling strength at an appropriate center of mass position as internal energies.
