Hey All,
I'm probably going to get railed for not searching hard enough for an answer to my idiotic question, but here goes anyways... The double slit experiment results go like this [correct me if I'm wrong here] 1/ One slit open > One band\probability dist. 2/ Two slits open > Interference Pattern 3/ Two slits open with detector at slit > 2 individual noninterfering bands\probability dist., essentially we've collapsed the wave function and forced the particle properties by "looking". I hope I've understood that at least  yes? So my question is  has anyone set up an experiment in a cold box with a thermally sensitive material for the slits and then shot hot particles onebyone, then measured any temperature gradients across the slits after registering on the other side of the wall? Would this be considered postentrance detection? Will the heat signature will still be there? Is this even possible? I'm guessing  there won't be any and we'll just get result #2? Just checking to see if this has been done or is not even required... Thanks in advance!
