classical monte carlo including more than first neighbor interaction
Dear ALPS community, is it possible to include more than nearest neighbor exchange in the classical Monte Carlo simulation within the Heisenberg model? For example the first 10 interactions (J11, J12, J13...) e.g. for an bcc bulk lattice? I suggest that this would exclude the possibility of cluster updates? Any help maybe including a small example inputfile is greatly appreciated, thanks a lot in advance :), Fritz --- Max-Planck-Institut für Eisenforschung GmbH Max-Planck-Straße 1 D-40237 Düsseldorf Handelsregister B 2533 Amtsgericht Düsseldorf Geschäftsführung Prof. Dr. Jörg Neugebauer Prof. Dr. Anke R.

yes, you just need to add the corresponding bonds to the lattice unit cell

Only if the interactions are frustrated.

Look at the "frustrated square lattice" example. This is a square lattice with 1st and 2nd neighbor interactions. I hope this helps Matthias
