[ALPS-users] request(Dzyaloshinsky-Moriya interaction)

Dear all I am interested to simulate Heisenberg spin chain in the presence of Dzyaloshinsky-Moriya interaction, but I don't know how to prepare an input file with Dzyaloshinsky-Moriya interaction. Actually, I am going to run full-diagonalization. I would be most grateful if anyone could give me some hand. Thank you very much in advance -- Best Regards Javad Vahedi,
