Dear Anton,
Now I understand.
The k values must not be in the units of the lattice constant, but in
units of the period of the Unit cell of the nanoribbon.
For the armchair nanoribbon, it just so happens that this periodicity is
sqrt(3) times the graphene lattice constant, meaning that
Dear George,
It isn't the energy scale that varies, but rather the momentum. It is
important to remember that the k-values are in the units of the inverse
period of the system whose band structure you are computing.
Best,
Anton

Dear Anton and Kwant team,
I have an important update: the energy becomes correct (in eV) if I
multiply its values by sqrt(3).
This makes no sense to me and I really cannot understand why I have to
multiply the energy by sqrt(3) to get the correct number in eV versus
nanometers^{-1}.

Dear Anton,
Thank you for your kind reply, I really appreciate any help given!
From your answer:
The unit of energy everywhere is the same as the one you use when
defining the Hamiltonian.
This does not correspond with what is returned by `kwant.physics.Bands`,
or I am doing some trivial
Dear George,
What does not make any assumptions about the units, leaving the
interpretation entirely up to you.
