Critical exponents of quantum Heisenberg model

  1. Feb 21, 2010 #1
    Hey guys, I ran some simulation of thermal phase transition of three dimensional quantum antiferomagnetic cubic lattice. I'm pretty happy with critical temperature, but I'm not sure about critical exponents because I'm having trouble locating some reference with their best known values. I know that [tex]\gamma[/tex] should be something like 1.41 and I'm in the ballpark there, but I don't know anything about [tex]\alpha[/tex], [tex]\beta[/tex] and [tex] \nu[/tex].

    Can anyone help me with this?
