    Hello
    Does anyone know about calculating feynman path integral with monte
    carlo method?

    In imaginary time?
    Throw a dice. Chose a path according to the weight exp(-S). (hint:
    Markov chain)

    Makri's group at Urbana-Champaign does that to solve certain difficult
    problems in large system quantum mechanics. Look up her papers. It's
    nontrivial.

    I'm sure people probably do it also for field theory, but I wouldn't
    know where to point you. Also stock market physicists do it as well.
