Dear all<br><br> I am interested to simulate Heisenberg spin chain in the presence of<br>
       Dzyaloshinsky-Moriya interaction, but I don&#39;t know how to prepare an<br>
       input file with Dzyaloshinsky-Moriya interaction.<br>
       Actually, I am going to run full-diagonalization.<br>
       I would be most grateful if anyone could give me some hand.<br>
       Thank you very much in advance<br clear="all"><br>-- <br>Best Regards<br>Javad Vahedi,<br><br>
