Dear Kwant Community,
I am writing to seek assistance with two issues I have encountered while using
Kwant for solving transport problems. Your guidance would be greatly
appreciated.
1. I am trying to calculate the Landau levels of monolayer graphene using the
following Hamiltonian (python):
```
hamiltonian = """
+ hbar_vF * (k_x * kron(sigma_0, sigma_x) + k_y * kron(sigma_0, sigma_y))
"""
params = dict(hbar_vF=6.582)
```
In the documentation for the `discretize_landau` function, it is stated that
"The units of magnetic field are :math:`ϕ₀ / 2 π a²` with :math:`ϕ₀ = h/e`
the magnetic flux quantum and :math:`a` the unit length."
Is a^2 here the area (A) of a primitive cell of graphene (A = 5.24 Ų)? How
can I convert this unit into Tesla?
2. Can I use this code to calculate the Landau levels of multilayer stacking
graphene with a sequences of hoppings ? Are there specific considerations or
modifications I should be aware of when extending the calculation to multilayer
graphene?
Thank you in advance for your help.
Best regards,
