The operational state of the photon-breeding devices, developed by T. Kawazoe and M. Ohtsu, lies far from the ground state, therefore, variational optimization of the action integral is essential in a theoretical exploration. This presentation discusses how the action integral, the induced current density, and the linear and nonlinear susceptibilities depend on the backward and forward causations that is mathematically available to solve Heisenberg equation.
