How should I use the standard mode to generate the following file for the expert mode?Just like the files you displayed

[shuailiu199966]

How can I generate the following file for expert mode using standard mode? I want to obtain the InterAll file for the model using standard mode. How should I proceed? I executed HPhi -sdry stan.in, but it did not produce an InterAll file.

In your InterAll file, it is mentioned that to ensure the generated Hamiltonian is a Hermitian matrix, the input needs to include both

and its Hermitian conjugate

.
How should I implement this in the InterAll file? For example, if I first input "2 0 2 1 3 0 3 1 -0.25 -0.25 ", do I need to continue inputting "3 1 3 0 2 1 2 0 -0.25 0.25"
Does this operation need to be performed for all interaction terms, or only for off-diagonal terms? For example, should this be done for the x-bond and y-bond directions in the Kitaev model, but not for the interaction terms in the z-bond direction?

In standard mode, if the specified interactions are represented by standard interactions such as Hund coupling, Exchange coupling, PairLift interactions, etc, input files are generated in the format of the standard interactions.

W = 2
L = 3
model = "SpinGC"
method = "CG"
lattice = "Honeycomb"
J0x = -1.0
J1y = -1.0
J2z = -1.0
2S=1
exct = 8

In this case, the Kitaev interactions are represented by CoulombInter , Hund, Exchange, and PairLift.
Thus, if you want to specify the Kitaev interactions in InterAll format, please make an input file manually.

You are right. The Hermitian conjugate pair is necessary in InterlAll format.

Does this operation need to be performed for all interaction terms, or only for off-diagonal terms?

You can specify both diagonal terms and off-diagonal terms in InterAll format.
In standard mode, the interactions that are not represented by the standard interactions such as J0xy
are represented in InterAll format.

For example, should this be done for the x-bond and y-bond directions in the Kitaev model, but not for the interaction terms in the z-bond direction?

You can represent all interaction in InterAll format and you can also mix InterAll format and other formats for the standard interactions. In this case, you can specify x-bond and y-bond interactions in InterAll format and represent z-bond interaction in Ising interaction format.

Can I manufacture a hexagonal honeycomb lattice using standard mode, as shown in the following figure

[ultimatile]

Please refer to the HPhi manual. The figure below is taken from Figure 4.2 in the manual.

If my understanding of your requirements is correct, the specifications for the interactions with the input file provided by tmisawa-san will change as follows according to the figure above:

J1x = -1.0
J2y = -1.0
J0z = -1.0

The 24-site honeycomb cluster can be defined in the following input file.

model = SpinGC
method = CG
lattice = Honeycomb
J0x = -1.0
J1y = -1.0
J2z = -1.0
a0W = 2
a0L = 2
a1W = 4
a1L = -2
exct = 1

This 24-site cluster consists of two 12-site loops and
topologically equivalent to your lattice.
You can check the geometry of this lattice by execting load ./lattice.gp in gnuplot.
I attached the lattice structure generated by gnuplot.
