Pairs of entangled photons are important for applications in quantum nanophotonics, where their theoretical description must accommodate bipartite character.Such character is shared at the other end intensity range by, example, two degenerate instances pump field involved second-harmonic generation.The and numerical simulation interaction nanophotonic structures with states light challenging regardless intensity, has technological applications.To address such a challenge, we develop here computational framework studying material light.The theory rests on symmetrized tensor product space copies an electromagnetic Hilbert space.For side, convenient T-matrix method extended to space.When response object one part state independent part, simple function typical single space.Such separable relevant, biphoton nanostructures.Nonseparable operators identified as adequate objects fully integrate non-linear effects sum frequency generation or parametric down-conversion.As example application, derive selection rules second-order processes rotational and/or mirror symmetries, verify them numerically different MoS2 clusters.
