Question Correlated polarized photons in GEANT4

From: Estela Suarez <Estela Suarez>

Hello,

I would like to simulate a laboratory setup in which two photons are correlated. This means, that they're produced in two opposite directions with perpendicular polarization vectors. Actually, to be more precise, the generated photon hasn't got a polarization direction until you measure it, and this fixes the polarization of the correlated photon.

Is it this phenomena already implemented in Geant4? And if not, can somebody suggest me some way in which I can implement it?

I've tried to launch a photon in one direction, and when it is detected in my detector, to launch the second one from the initial point with opposite momentum and perpendicular polarization. The problem is that those two photons are not really correlated, and G4 treats them as completely independent photons (so the polarization that I get as a result is not correct).

I would be very thankful if somebody could suggest how to accurately reproduce that phenomena.

Thanks in advance, Estela.
