Cavity-Assisted Remote Energy Transfer

Strong molecule-light interaction enables the control of molecular structures and dynamical processes. A molecular model is proposed to greatly enhance the intermolecular distance of resonant energy transfer, where the molecules are strongly driven by an optical cavity. The optimal intermolecular distance and quantum yield of energy transfer are observed, resulting from the balance between dipole-dipole interaction and molecule-cavity coupling. Our approach is {\textit{non-perturbative}}, going much beyond the Forster mechanism of resonant energy transfer. Our work sheds the light on the spectroscopic study of the cooperative energy transfer in molecular polaritons.
