Ising model canonical partition function

  1. Feb 23, 2013 #1
    Why in case of Ising model ##H=-J\sum S_iS_{i+1}## we calculate canonical partition function?

    Your question is tough to interpret.

    Can you try rephrasing it?

    I suppose yes. Well you calculate partition function Z. Like sum over all ##\{S\}## of ##e^{-\beta H}##. Why is that canonical partition function and not microcanonical for example?
