Hello,<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; I am having a little difficulty
understanding the tutorial for ALPS version 2. Is their a difference
between the rectangular lattice and square lattice? If we set the
coupling itself in 2d(J0 and J1) then does relative distance matter or
is distance and coupling strength two separate factors that make up an
effective coupling strength?<br>
<br>
