Towards spontaneous parametric down conversion from monolayer MoS2. [PDF]
Sci Rep, 2018 AbstractWe present a detailed study of the second order nonlinearity of 2D (mono-atomic layer) dichalcogenide MoS2, both in the visible and in the IR regime, and test its potential for spontaneous parametric down-conversion (SPDC), the amplification of vacuum fluctuations mediated by optical nonlinearity.

Angular Schmidt modes in spontaneous parametric down-conversion [PDF]
Physical Review A, 2011 We report a proof-of-principle experiment demonstrating that appropriately chosen set of Hermite-Gaussian modes constitutes a Schmidt decomposition for transverse momentum states of biphotons generated in the process of spontaneous parametric down conversion.

Time ordering in spontaneous parametric down-conversion [PDF]
AIP Conference Proceedings, 2011 We consider the multi‐mode parametric down‐conversion Hamiltonian that governs the evolution of the fields inside a nonlinear crystal. If the Hamiltonian does not commute with itself at all times—as is the case for the multimode down‐conversion Hamiltonian—then the expansion of the evolution operator must take the form of the time‐ordered Dyson series,

Nonseparable Werner states in spontaneous parametric down-conversion [PDF]
Physical Review A, 2006 The multiphoton states generated by high-gain spontaneous parametric down-conversion (SPDC) in presence of large losses are investigated theoretically and experimentally. The explicit form for the two-photon output state has been found to exhibit a Werner structure very resilient to losses for any value of the gain parameter, g. The theoretical results
