Hi everybody, I'm trying to simulate double slit experiment for electron (or any particles) by monte carlo method.but there is something interesting here which I explain it for you. I supposed that electron will pass one of the splits in each time (by same chance) with random angle in X direction (according to uncertainty principle).results was classically predicted and violate experiment results! Feynman have reported this result would be appear if you want to know where the electrons go.There are some electrons which pass two split at the same time but how can show it in monte carlo simulation? should i just consider wave properties of electron (I mean wave function) or ... ? (But I really want to understand this without using wave function) Thanks a lot.
