Calculating Landau Levels of a Honeycomb Lattice about pyqula HOT 1 CLOSED

Dear ac76888,

thanks for the message. To compute Landau levels you need to have a one dimensional Hamiltonian. geometry.honeycomb_ribbon(30) is a one dimensional geometry, whereas specialhamiltonian.multilayer_graphene(l='AB',ti=0.2) is a two-dimensional Hamiltonian. In principle, Landau levels can only be computed with one-dimensional Hamiltonians for arbitrary magnetic fields. You can transform a two-dimensional Hamiltonian into a one-dimensional one with

from pyqula import ribbon
h = ribbon.bulk2ribbon(h,n=60)

you can also find an example in

Best regards,
