Hi
I simple want to write a script for 2d square lattice, with AFM Heisenberg
interaction on nearest and next nearest neighbor bonds.
How do I know if naming them respectively J0, and J1 (both AFM) should
work or not? If I name them instead J1 and J2 should that work?
My input file presently looks like:
parms.append(
{
'LATTICE' : "frustrated square lattice",
'T' : t,
'J0' : -1 ,
'J1' : -0.5 ,
'THERMALIZATION' : 10000,
'SWEEPS' : 500000,
'UPDATE' : "cluster",
'MODEL' : "Heisenberg",
'L' : 8,
'W' : 8
}
)
I want NN J to be 1.0 and NNN J to be 0.5. Is that going in properly?
The term "frustrated" in front of "square lattice", should that be
necessary? What would be the extension of the name for the lattice when I
do a cubic lattice, say, with J1 (NN), J2 (NNN), J3(NNNN)? How do I know in
that case which direction is preferentially x, y and z? Thanks in advance
for all the replies.
