| | ====== Options ====== |
| | |
| | The last element of CreateClusterHamiltonian can be a table of options. Possible options are: |
| | * "AddSpin": Boolean for including spin in the output Hamiltonian operator. (standard value false) |
| | * "ReturnTBSuperCell": Boolean for returning the output tight-binding object. (standard value false) |
| | * "ReturnTBCellPositions": Boolean for returning the lattice vectors of the output periodic cluster. (standard value false) |
| | * "ReturnTBKVectors": Boolean for returning the reciprocal lattice vectors of the output periodic cluster. (standard value false) |
| | * "ReturnTBIndicesDict": Boolean for returning the dict for the indices defined for the output Hamiltonian operator (see //[[documentation:language_reference:functions:CreateAtomicIndicesDict|CreateAtomicIndicesDict()]]//). |
| | * "k": possible phase-shift in the hopping matrix elements of the output Hamiltonian operator. (standard value {0,0,0}) |
