Dear sir,
That is exactly what I am looking for.
But in my case Hamiltonian is not polynomial in k. It contains Sine and
Cosine terms. It's a tight binding Hamiltonian having coupling terms like
sigma_x *Sin(kx)+ sigma_y *sin(ky) and mass term in the trignometric form.
So, can I proceed by writin
The second problem is solved. I got the landau fan for BHZ model.
Thank you for the support.

Dear sir,
I have updated KWANT, but it shows the *AttributeError: module
'kwant.continuum' has no attribute 'discretize_landau'.* And in browser
also, it is showing the same error. I have downloaded the landau_levels.py
file and put it into the continuum folder. But it is not working.

Great,
Just to add a concluding remark: Landau fan requires a continuum
approximation of the Hamiltonian. If you start with a tight-binding
Hamiltonian you'd get fractal spectrum and the Hofstadter butterfly
instead.
Happy Kwanting,
Anton
