code for heisenberg model on fcc lattice
Dear friends. I would appreciate if you could help me with using classic montecarlo simulation for fcc lattice on Heisenberg hamiltonian with s=1 and H=SIGMA Jij Si.Sj and Jij is just sum over nearest neibours.Would you mind telling me step by step that what should I do and exactly which codes I must use for this purpose?Its the first time I wanna use Alps and I dont know the steps of working with it. Many thanks for your helps. I would appreciate your immediate attention to this matter.
Are the couplings all antiferromagnetic? If so there is no way around the sign problem. On Dec 5, 2012, at 4:14, sh po <quin_girl_sh@yahoo.com> wrote:

I've prepared simple example programs for classical Heisenberg models. Please download the latest ALPS (revision 6650 or later) and look at example/parapack/heisenberg Best, Synge On 2012/12/05, at 21:14, sh po <quin_girl_sh@yahoo.com> wrote:
