Young's Double Slit Experiment: Is it Possible?

[Heidi]

I think that it is harder to describe the two slits Young experiment in terms of hamiltonian because the particle has a constraint: to pass through the slits. is it possible?
thanks.

How do you describe it without Hamiltonian?

 

[Heidi]

my question is about the constrained hamiltonian if it is used. i do not says it does not exist. we may have H=0 with constrained hamiltonians so problems raise.
more generally can we use the feynman paths when the paths are constrained to live on a given surface (say a 4 sphere)
