A. Bandilla et al., SUB-POISSONIAN PHOTON STATISTICS IN A 3-WAVE INTERACTION STARTING IN THE OUT-OF-PHASE REGIME, Physical review letters, 75(22), 1995, pp. 4019-4022
We present for the first time numerical and analytical calculations fo
r the nonlinear interaction of three quantized waves all sizably excit
ed from the beginning and having different phase relations. With a Ker
r-state ansatz for the signal we get strongly sub-Poissonian photon st
atistics and conclude on similar effects by initially entangled states
.
