Dear Santu,

Yes you can easily do that with Kwant.

- An example of 2 atoms per unit cell is given in
https://kwant-project.org/doc/1/tutorial/graphene

- An example of multiorbital (in this case it is spin but orbitals are totally equivalent)
is given in
https://kwant-project.org/doc/1/tutorial/spin_potential_shape

Best regards,

Xavier

Dear Kwang users,

  I have recently started using Kwant for making model Hamiltonian. It is really very good python package. I have started learning some tutorials. I would like to know if making tight-binding Hamiltonian with multi atom and multi orbital basis possible using Kwant. I can not find such example in documentation. I would like to then try to make a honeycomb lattice with two atoms and each atom with two basis, e.g., px, py.

Please help me to know about this in more detail.
Thanking you,

Santu B
