Hi,
Thank you so much for your mail. My input for kitaev-heisenberg is LATTICE_LIBRARY="lattices.xml" MODEL_LIBRARY="models.xml"
MODEL="kitaev heisenberg" LATTICE="honeycomb lattice"
local_S = 0.5 W=3 J = 1 Jx = 0 Jy = 0 Jz = 0 {L=3;}
though i havnt changed the lattices.xml file. And for the spin
MODEL="spin" LATTICE="honeycomb lattice"
local_S = 0.5 W=3 J = 1 {L=3;}
Regards

Hi,
I am writing a code for the computing gap in kitaev-heisenberg model on
the honeycomb lattice using sparse diagonalization. When the coupling for the kitaev term is zero the model patch that I wrote should match the model that is inbuilt. But that doesnt happen. I may have made a mistake in the model patch which is as follows.
<HAMILTONIAN name="kitaev heisenberg"> <PARAMETER name="J" default="1"/> <PARAMETER name="Jz" default="0"/> <PARAMETER name="Jx" default="0"/> <PARAMETER name="Jy" default="0"/> <BASIS ref="spin"/> <BONDTERM source = "i" target="j"> J*Sz(i)*Sz(j) +J*exchange_xy(i,j) </BONDTERM> <BONDTERM type="0" source="i" target="j"> Jz*Sz(i)*Sz(j) + J*Sz(i)*Sz(j) +J*exchange_xy(i,j) </BONDTERM>
<BONDTERM type="1" source="i" target="j"> Jx*Sx(i)*Sx(j) + J*Sz(i)*Sz(j) +J*exchange_xy(i,j) </BONDTERM>
<BONDTERM type="2" source="i" target="j"> Jy*Sy(i)*Sy(j) + J*Sz(i)*Sz(j) +J*exchange_xy(i,j) </BONDTERM> </HAMILTONIAN>
I have also attached the output that I got in dat format. Could you
please help me with this problem?
