Hi,
Thanks for the reply. I would also like to know if the anisotropy can be varied throughout the lattice, i.e. different values for different sites, or is only one value throughout the whole lattice allowed?
It can be varied by specifying different site types. The coupling parameters can also be chosen randomly or as a simple function of the site coordinates. What exactly do you have in mind?
Additionally I would like some points regarding the lattice definitions to be confirmed.
- The edge type 0,1,2 corresponds to bond type J0, J1 ,J2
parameters? Edge type default = 0?
- The edge offset is in units of 'basis vectors' specified in the
<BASIS> tags? Default = 0 0 0? Allowing both -ve and +ve numbers?
Thanks,
Yes to all of the above
