摘要：

The nonlinear susceptibility chi(3) and the four-wave mixing signal from assemblies of molecules with nonoverlapping charge distributions and an arbitrary geometry are calculated using Green's-function techniques. At low molecular density and under off-resonant excitation we recover the local-field approximation. The role of retarded interactions and cooperative spontaneous emission in the electro-dynamics of confined excitons in molecular quantum wells is discussed.
